Who Is Diane Keaton’s Husband? Marriage, Partners, Kids Explained

There is no Diane Keaton husband. The Oscar-winning actor never married. Interest in her personal life has surged again following her death on October 11, 2025, in California.

Diane Keaton’s Relationship History and Family

Never married. Keaton confirmed across many interviews that she did not wed. She kept long-term relationships private and on her terms.

High-profile partners. She dated Woody Allen in the early 1970s during their stage and film collaborations. She was later in a widely discussed relationship with Warren Beatty around the time of Reds (1981). She also had an on-and-off relationship with Al Pacino across the years surrounding The Godfather films. None led to marriage.

Two children by adoption. Keaton adopted a daughter, Dexter, in 1996. She adopted a son, Duke, in 2001. She often emphasized how motherhood reshaped her life.

Career-first choice. Keaton’s decision aligned with her independent public persona. She balanced studio comedies, prestige dramas, and directing while keeping her home life deliberately simple.

Public confusion explained. Fans sometimes assume she married a co-star due to on-screen chemistry. The most common speculation links her to Al Pacino because of their roles as Michael and Kay. The record is clear. They did not marry.
