This is a list of notable elections involving accusations of direct voter fraud or in which the results were procedurally contested, extensively protested, or recognized as fraudulent by a reliable international organization.

• 2011 Canadian federal election - During the Robocall scandal, Elections Canada and the Royal Canadian Mounted Police investigated widespread reports of robocalls from Conservative Party campaign offices misleading voters from casting ballots by claiming that their polling stations had been changed, an act of electoral fraud and voter suppression under the Canada Elections Act. Although the investigation was initially centered around the riding of Guelph, Ontario, further instances were reported around the country, leading to widespread protests. Although the Commissioner of Canada Elections ultimately refused to press charges against the Conservative Party, a junior staffer named Michael Sona was ultimately convicted of voter fraud.[15][16][17][18][19][20][21]
• 1988 Mexican general election - The election was the first in which Mexico introduced a parallel vote tabulation system in which electoral districts report results by telephone to the Secretariat of the Interior. Although early results showed the National Democratic Front (FDN) candidate Cuauhtémoc Cárdenas in the lead, Secretary of the Interior Manuel Bartlett claimed that the new voting system had broken down, and the Institutional Revolutionary Party (PRI) candidate Carlos Salinas de Gortari ultimately was declared the winner. In 1991, President Miguel de la Madrid admitted in his autobiography that the breakdown had been faked and that there were no complete results when Salinas de Gortari was declared the winner. The result was the lowest performance for any winning President since the institution of direct elections for the presidency under the 1917 Constitution, and the PRI's worst electoral performance since dominating Mexican politics after 1929.
• 2006 Mexican general election - The election was plagued by irregularities, and President Vicente Fox was accused of using his government to favor the National Action Party candidate Felipe Calderón over the initially heavily-favored Party of the Democratic Revolution candidate Andrés Manuel López Obrador. After Calderón won the election Mexico was plagued by nationwide civil unrest, including widespread protests in Oaxaca. Most analysts believed Calderón launched the Mexican Drug War to cement his legitimacy amid the instability.
• 2012 Mexican general election - After the PRI candidate Enrique Peña Nieto was declared the winner, the Yo Soy 132 movement emerged protesting the results due to reports that the PRI had participated in campaign finance violations, electoral fraud, and vote buying by providing poor voters with Soriana store credit cards. Although Peña Nieto was eventually redeclared the winner after a recount endorsed by the United States, unrest continued through Peña Nieto's inauguration.
• 1792 New York gubernatorial election – The Federalist Party candidate John Jay received more votes than the Democratic-Republican Party candidate George Clinton, but on technicalities the votes of Otsego, Tioga and Clinton counties were disqualified and not canvassed, giving George Clinton a slight majority in the official result.
• 1824 United States presidential election - John Quincy Adams became President after winning a contingent election in the House of Representatives due to the absence of a two-third majority in the Electoral College despite the fact that Andrew Jackson, who would win the 1828 presidential election outright, won a plurality of the popular and electoral vote.
• Bleeding Kansas election, March 30, 1855 – An election to decide whether Kansas should be a free state or a slave state involving massive immigration to sway the vote and resulted in post-election violence, including a severe beating of a US Senator by a Congressman. The events it encompasses directly presaged the American Civil War. (See Kansas–Nebraska Act)
• 1876 United States presidential election – One of the most disputed and controversial presidential elections in American history between the Democratic Party's candidate Samuel J. Tilden and the Republican Party's candidate Rutherford B. Hayes, resolved by the Compromise of 1877, which allowed Hayes to become President in exchange for the end of Reconstruction and the withdrawal of federal troops stationed in the South after the American Civil War. Although it is generally agreed that Tilden won a majority of the popular vote, the results of the electoral vote continue to be disputed.
• 1888 United States presidential election - The incumbent Democrat President Grover Cleveland won a majority of the popular vote, but Benjamin Harrison won the electoral vote. Cleveland would later be reelected in the 1892 presidential election.
• 1891 New York State Senate election in Dutchess County
• 1948 United States Senate election in Texas - Lyndon B. Johnson won the Democratic primary over Coke R. Stevenson by only 87 votes. However, Johnson was accused of voter fraud in Duval County, as initially it appeared Stevenson had won but later on more votes were allegedly found for Johnson.
• 1960 United States presidential election[22] - Some accounts claimed that mobster Sam Giancana and his Chicago crime syndicate played a role in Kennedy's victory in Illinois.[22]
• 2000 United States presidential election - After a close election in which the winner was unclear, the Republican candidate George W. Bush won Florida by such a slim margin that a recount of the votes was triggered under Florida state law, beginning a series of legal battles between Bush and the Democratic candidate Al Gore and considerable public controversy. After the completion of a machine recount, the Florida Supreme Court ordered a manual recount due to continued concerns over the validity of the election. The case was appealed to the Supreme Court, which halted the recount in the Bush v. Gore and Bush v. Palm Beach County Canvassing Board decisions, allowing Bush to capture the State of Florida by a 0.0009 percent margin and win the electoral vote.
• 2002 Alabama gubernatorial election - Although the incumbent Democratic Governor Don Siegelman was initially declared the winner by a close majority, the Republican candidate Bob Riley ultimately won after a recount in Baldwin County without the presence of Democratic observers.
• 2002 New Hampshire Senate election phone jamming scandal[23] - During the 2002 United States Senate election in New Hampshire, the New Hampshire Republican State Committee hired a telemarketing firm to jam the phone bank used by the Democratic Party in a "get out the vote" operation. The Republican candidate John E. Sununu won a narrow victory over the Democratic candidate Jeanne Shaheen, while James Tobin was charged for lying to the FBI.
• 2004 Washington gubernatorial election - After a close election in which the Republican candidate Dino Rossi was declared the winner in the initial election and the machine count, the Democratic candidate Christine Gregoire was declared the winner after a manual recount. Rossi made an unsuccessful legal challenge to the results and did not officially concede the election for seven months.
• 2008 United States Senate election in Minnesota - The Republican incumbent Norm Coleman initially led against the Democratic-Farmer-Labor Party candidate Al Franken, but the close margin triggered a mandatory recount under Minnesota state law, and Franken was ultimately declared the winner by the Minnesota State Canvassing Board.
• 2016 United States presidential election - The election was widely characterized as divisive and negative and was plagued by scandals such as the Republican candidate Donald Trump's alleged sexual misconduct and the Democratic candidate Hillary Rodham Clinton's alleged improper use of an email server. No Russian citizen accused of interfering in the election in the form of online influencing from a St. Petersburg-based troll farm has been formally charged and as result no Court will have the opportunity to review evidence to support or dispute accusations of Russian interference that adhere to the standards of the United States Judicial System for proving guilt. Trump ultimately won an upset victory in the Electoral College despite Clinton's victory in the popular vote, and characterized the Russian interference as a "hoax" and "fake news" despite the conclusions of the U.S. intelligence community to the contrary. In 2016, the FBI initiated the Crossfire Hurricane investigation over the Russian meddling in the election and links between Trump associates and Russian officials, and President Trump dismissed FBI Director James Comey due to his continuation of the investigation. Due to allegations of collusion with the Russian government, Deputy Attorney General Rod Rosenstein appointed Robert Mueller as Special Counsel to lead an investigation. Although the investigation resulted in 34 indictments and 8 criminal convictions, it was refraining from making a judgment about whether Trump could be criminally charged for obstruction of justice due to his conduct during the investigation. In 2020 US Attorney General William Barr initiated a criminal investigation of the Rosenstein/Mueller collusion investigation in response to its questionable basis and procedures.
• 2017 United States Senate special election in Alabama - During the election to fill U.S. Attorney General Jeff Sessions's vacated Senate seat in Alabama, the Republican Party candidate Roy Moore refused to concede the election after being defeated by the Democratic Party candidate Doug Jones despite pressure from his ally President Donald Trump's administration to do so, claiming that he had been the victim of a voter fraud conspiracy. Moore was additionally plagued by sexual misconduct allegations, including allegations of child molestation.
• 2018 Georgia gubernatorial election - Brian Kemp retained his post as Georgia Secretary of State after his nomination by the Republican Party for Governor of Georgia, leading to conflict of interest allegations. Due to irregularities in voter registration the Republican state government was accused of voter suppression, while U.S. District Court Judge Leigh Martin May ruled that Gwinnett County violated civil rights law by rejecting absentee ballots. After the election was re-certified, the Democratic Party candidate Stacey Abrams ended her campaign but refused to concede the election.
• 2020 Iowa Democratic caucuses - The Iowa Democratic Party was initially unable to collect and announce results due to the failure of a mobile application designed to collect the votes. Although the results were eventually released with Pete Buttigieg leading, they have been subject to scrutiny and the Democratic National Committee Chairman Tom Perez has advocated a recanvassing of the votes.
• 2020 Wisconsin Democratic primary - During the COVID-19 pandemic, Tony Evers, Wisconsin governor moved to delay the primary election because voters were expected to shelter in place to minimize the spread of the virus. The Wisconsin Supreme Court stepped in and ruled that this was not allowed. The U.S. Supreme Court also ruled 5:4 that the election would take place as scheduled, disregarding the fact that only 5 of the 180 polling places would be open due to a lack of poll workers, due to the coronavirus pandemic. President Donald Trump stated, “The things they had in there [the Coronavirus Aid, Relief, and Economic Security Act] were crazy. They had things — levels of voting that, if you ever agreed to it, you’d never have a Republican elected in this country again.” It is fair to note that a seat for the Wisconsin State Supreme Court was on the ballot.
