Party of Five is an American teen and family drama television series created by Christopher Keyser and Amy Lippman that originally aired on Fox from September 12, 1994, to May 3, 2000, with a total of six seasons consisting of 142 episodes. The series featured an ensemble cast led by Scott Wolf as Bailey, Matthew Fox as Charlie, Neve Campbell as Julia, and Lacey Chabert as Claudia Salinger, who with their baby brother Owen (played by several actors) constitute five siblings whom the series follows after the loss of their parents in a car accident. Notable co-stars included Scott Grimes, Paula Devicq, Michael Goorjian, Ben Browder, Jeremy London, and Jennifer Love Hewitt. While categorized as a series aimed at teenagers and young adults, Party of Five explored several mature themes, including substance and domestic abuse, teen pregnancy, mental illness, cancer, and the long-term effects of parental loss.

Despite receiving positive reviews from television critics after its debut, including TV Guide naming it "The Best Show You're Not Watching" in 1995, the series suffered from low ratings during its first and second seasons, during which speculation arose that it would soon be cancelled. In 1996, Party of Five won the Golden Globe Award for Best Television Series – Drama, after which ratings and popularity grew for the majority of the remainder of the series.

A spin-off, Time of Your Life, starring Hewitt, debuted on Fox on October 25, 1999, and was cancelled after one season and 19 episodes.
