Troy Garity is son of actress Jane Fonda and activist/politician Tom Hayden. He is grandson of Henry Fonda, nephew of Peter Fonda, and cousin of Bridget Fonda. His half-sister is Vanessa Vadim.

Garity was given his paternal grandmother's surname, and his given names were in reference to two militant activists.

In 2006 Garity became engaged to Simone Bent, an African-American actress who has worked with the Rising Sun Theater Company in NYC and made a short film called Escape from Eden. She also managed the Mercer Bar in NYC. Jane Fonda encouraged the relationship, referring to Simone as her "future daughter in law" and her "son's fiancee" before the engagement.
