Diane Keaton was an American actress. Her career spanned more than five decades, during which she rose to prominence in the New Hollywood movement. She collaborated frequently with Woody Allen, appearing in eight of his films. Keaton received various accolades, including an Academy Award, a BAFTA Award, and two Golden Globe Awards, along with nominations for two Emmy Awards and a Tony Award. She was honored with the Film at Lincoln Center Gala Tribute in 2007 and the AFI Life Achievement Award in 2017.

Keaton had romantic associations with several high-profile entertainment-industry personalities, starting with Woody Allen when she played a role in the 1969 Broadway production of Play It Again, Sam, which he had written. Their relationship turned romantic following a dinner after a late-night rehearsal. Her sense of humor particularly attracted him. They briefly lived together during the production, but by the time the film came out, in 1972, their living arrangement had become more informal. They worked together on eight films between 1971 and 1993, and Keaton said that Allen remained one of her closest friends.

Keaton also had a relationship with her Godfather Trilogy co-star Al Pacino. Their on-again, off-again relationship ended after the filming of The Godfather Part III. Keaton said of Pacino, "Al was simply the most entertaining man ... To me, that's, that is the most beautiful face. I think Warren [Beatty] was gorgeous, very pretty, but Al's face is like whoa. Killer, killer face."

Keaton was already dating Warren Beatty in 1979 when they co-starred in the film Reds (1981). Beatty was a regular subject of tabloid and other media coverage, and Keaton became included, much to her bewilderment. In 1985, Vanity Fair called her "the most reclusive star since Garbo". This relationship ended shortly after Reds wrapped. Troubles with the production are thought to have strained the relationship, including numerous financial and scheduling problems.

In her 50s, she adopted two children — a daughter in 1996 and a son in 2001. She later stated: "Motherhood has completely changed me. It's just about the most completely humbling experience I've ever had."

Keaton died in Los Angeles, California, on October 11, 2025, at the age of 79. Her health had declined significantly in the preceding months, though she remained private about her condition.
