2018 US Open
Champion	Naomi Osaka
Runner-up	Serena Williams
Final score	6–2, 6–4
Draw	128 (16Q / 8WC)
Seeds	32

Sloane Stephens was the defending champion, but was defeated in the quarterfinals by Anastasija Sevastova, in a rematch of the previous year's quarterfinals.

Naomi Osaka won her first Grand Slam title, defeating Serena Williams in the final, 6–2, 6–4. At the age of 20, Osaka became the first Japanese person to win a Grand Slam singles title and the youngest US Open champion since Maria Sharapova in 2006. In virtue of her victory, Osaka also made the top 10 for the first time, debuting at No. 7.^[1][2]

Simona Halep's first-round loss to Kaia Kanepi marked the first time in the Open Era that the top seed lost in the first round of the women's singles of the US Open.^[3] Despite her loss, Halep retained the WTA No. 1 singles ranking at the end of the tournament.

The losses of Halep in the first round and Caroline Wozniacki in the second round marked the first time that neither of the top two seeds advanced past the second round of the US Open women's singles event, and the second time this happened at any Grand Slam event in the Open Era (following the 2014 French Open).
