Her family confirmed that pneumonia was the cause of her death on October 11, 2025.

The Final Months: A Sudden Health Decline
Friends close to Diane Keaton revealed that her health had declined very suddenly in the months leading up to her death.

One close friend shared that Keaton was surrounded only by her closest family during her final days, emphasizing the intimate and private nature of her last moments.

Sager described being stunned by the visible changes in Diane’s appearance during a recent visit, highlighting the severity of her health struggles.
Despite her illness, Diane Keaton remained true to herself until the end. A film executive friend recalled that she maintained her humor and lived life on her own terms, surrounded by the people and things she loved most.
