  Son of Mr. Logan (deceased) and Helen Logan (deceased). Patriarch of the Logan family. Ex-husband to Beth Henderson. Father to Stephen "Storm" Logan, Brooke Logan, Donna Logan and Katie Logan. Has a rivalry with Stephanie Forrester due to the way that she has treated his daughters, Brooke and Donna. He dated Stephanie's sister Pam Douglas, and tried to convince her to shoot Stephanie, but it was Stephanie who shot him. He passed a period in jail, but now, thanks to Bill Spencer Jr., he was set free.

Second generation

• Stephen "Storm" Logan Jr. (William deVry)
  Eldest child and only son of Stephen Logan and Beth Henderson, born on December 13, 1964. Was very protective of his younger sisters and had to act as a father figure since their father Stephen was not there very often. Storm was a lawyer and has defended many people on the show. He was engaged to Taylor Hamilton. He shot Stephanie Douglas after the way she had treated Donna, and tried to frame his father Stephen for the crime. This showed that Storm still had unresolved issues with his father. He then accidentally shot his sister Katie Logan, and when she needed a heart transplant as a result, he took his own life to give his sister his heart.
• Brooke Logan (Katherine Kelly Lang)
  Eldest daughter of Stephen and Beth Henderson, born on June 28, 1966.

She is the mother of Rick Forrester, Bridget Forrester, Hope Logan, R.J. Forrester. and Jack Hamilton Marone. She works at Forrester Creations.

A former CEO of Forrester Creations due to blackmailing the Forrester family who tried to steal her invention, she was a part of Forrester Originals when it started.
• Donna Logan (Jennifer Gareis)
  Daughter of Stephen and Beth Henderson, born in 1969. She had an affair with her sister Katie's fiancé Rocco Carner in 1989. In 2006 she began a relationship with Ridge Forrester Sr. She was engaged to Thorne Forrester, but the wedding was cancelled when it was revealed Donna was using Thorne to get back at Stephanie Forrester. She is the mother of Marcus Forrester, biological son of Justin Barber but adopted by Eric Forrester during Donna's marriage to Eric.
• Katie Logan (Heather Tom)
  Youngest child of Stephen and Beth Henderson, born in 1970. Early in life she was perceived as the "ugly duckling" of the Logan family. She had a platonic relationship with Thorne Forrester. She was shot by her brother, Storm, and needed a heart transplant. Storm committed suicide to give Katie his heart. Her body was rejecting the transplanted heart, but her niece/physician Bridget found a cure, and Katie's life was saved. Katie had a baby with Nick Marone while he was married to Bridget. She is the mother of Will Spencer, third son of Bill Spencer.

Third generation

• Eric "Rick" Forrester Jr. (Jacob Young)^[1]
  Son of Brooke and Eric Forrester. As a child he shot Grant Chambers, but repressed the memory. In his late teens to early 20s, he was married to Amber Moore twice. He spent time in Paris, working at Forrester International. After Nick Marone blackmailed Eric into selling him the company, Rick returned from Paris and developed an antagonistic relationship with step-father Ridge Forrester, ostensibly due to Ridge's treatment of Brooke. Rick has romanced Ridge's daughters Phoebe and Steffy, and was briefly engaged to their mother Dr. Taylor Hayes. He is the husband of Maya Avant Forrester and father of Lizzy Forrester.

He is the father of Ambrosia "Rosie" Barber Forrester.
• Hope Logan (Annika Noelle)
  Daughter of Brooke and Deacon Sharpe, born onscreen in 2002. Her paternity was hidden because Deacon was married to Brooke's daughter Bridget at the time. Brooke wanted Nick Marone, but the plan fell through. Hope had a relationship with Oliver Jones, but it was over when she discovered he had sex with her mother. Hope was engaged to Liam Spencer, but she called off the engagement. She was married to Liam's older half brother Wyatt Spencer.
