Diane Keaton has had her cause of death officially disclosed.
On Wednesday, October 15, Keaton’s family released a statement to People confirming that the Oscar-winning actress passed away from pneumonia on Saturday, October 11.
In their statement, the Keaton family expressed their gratitude for the outpouring of support, stating, “The Keaton family is deeply appreciative of the incredible messages of love they’ve received during this difficult time following the loss of their beloved Diane, who left us on October 11 due to pneumonia.”
Furthermore, Keaton’s family highlighted her remarkable life by saying, “She cherished her pets and was unwavering in her advocacy for the homeless community, so contributions in her name to a local food bank or an animal shelter would be a beautiful tribute.”
Us Weekly has reached out to Keaton’s representatives for further comments.
A representative for the late actress confirmed on Saturday, October 11, that she was 79 years old at the time of her passing, though additional details were not provided initially. Her family, including daughter Dexter and son Duke, requested “privacy” as they mourned her loss.

A close friend of Keaton’s later informed People that her health had “declined very suddenly” in her last months, noting that she opted to withdraw from the public eye to be with her “most cherished family.” Reports also indicated that sightings of her walking her dog, Reggie, came to an end shortly before her passing.
At the time of her passing, Keaton was in the midst of selling her expansive 9,200-square-foot property in the Sullivan Canyon area of Los Angeles, despite having chronicled its extensive renovations in her 2017 book, The House That Pinterest Built. After initially listing it for $28.9 million, she reduced the price by $1.4 million in March to hasten the sale.
Her final Instagram post was made in conjunction with Hudson Grace, the home décor company that sold her collection, celebrating National Pet Day in April, featuring her adored golden retriever, Reggie, showcasing products from her line.
“Proof our pets have excellent taste too,” she wrote at that time. “Happy National Pet Day from HG & Diane Keaton.”

With an illustrious Hollywood career that spanned almost six decades, Keaton claimed the Best Actress Oscar for her iconic role in the 1977 comedy, Annie Hall, and received three additional nominations throughout her career for her performances in the 1981 political drama Reds, the 1996 family drama Marvin’s Room, and the 2003 comedy Something’s Gotta Give.
Her rise to fame began with her unforgettable portrayal of mob wife Kay Adams-Corleone alongside Al Pacino in 1972’s The Godfather. Keaton became a prominent figure in various comedies directed by her then-boyfriend Woody Allen during the 1970s, including Annie Hall, Love and Death, and Manhattan.
By the early 1990s, Keaton expanded her talents into directing music videos and television episodes, notably contributing to the groundbreaking series Twin Peaks in 1991. She returned to acting with notable success in the acclaimed drama Marvin’s Room and the hit comedy The First Wives Club in 1996, the latter becoming her largest commercial success of the decade.
Up until shortly before her passing, Keaton remained active in the film industry, most recently collaborating with Kathy Bates and Alfre Woodard on the upcoming 2024 comedy Summer Camp.
In the wake of her passing in October 2025, Keaton’s co-star from First Wives Club, Bette Midler, honored her memory, describing her as one of a kind within the Hollywood landscape.
“The brilliant, beautiful, extraordinary Diane Keaton has passed away,” Midler expressed on Instagram on October 11. “Words cannot describe the sorrow I feel.”
Midler elaborated, “She was comedic, one of a kind, and utterly genuine, devoid of guile or the competitiveness expected of someone in her position. What you saw was who she truly was… oh, la, lala!”
Goldie Hawn‘s daughter, Kate Hudson, also paid tribute by sharing a classic clip from First Wives Club via Instagram and added the heartfelt caption: “We love you so dearly, Diane.”
