Diane Keaton’s Cause of Death Confirmed by Family

The official cause of death has been listed as primary bacterial pneumonia, according to her family. The Oscar-winning actress, best known for her iconic roles in Annie Hall, The Godfather, and Father of the Bride, reportedly experienced a sudden decline in her health in the days leading up to her death.

A family member confirmed that Keaton was in California at the time of her passing and was surrounded by loved ones in her final moments. She was cremated on October 14, just days after her death.

Keaton’s family also encouraged fans to honor her memory by donating to local shelters or food banks, reflecting her lifelong dedication to helping those in need and supporting the unhoused community.

The actress had faced various health challenges throughout her life, including skin cancer and an early struggle with bulimia, but had not publicly disclosed any major health issues before her death. Reports noted that she appeared active and engaged earlier this year, although those close to her noticed a rapid decline shortly before October.

Keaton is survived by her two adopted children, Dexter and Duke. She adopted Dexter in 1996 and Duke in 2001, often speaking about how motherhood profoundly shaped her life and career.
