Comedian Phyllis Diller -- who paved the way for today's female comics -- died yesterday morning, TMZ has learned.
Sources close to Diller tell us the comedian died in her sleep at her L.A. home, surrounded by family. She was 95.
We're told Diller had recently fallen, hurting her wrist and hip -- but her rep says the injury had nothing to do with her death.
Diller suffered a heart attack in 1999 and was later fitted with a pacemaker.
Phyllis began her career all the way back in 1952 -- and rose to fame with her TV specials alongside Bob Hope in the 1960s.
Later that decade, Phyllis starred in her own show called "The Phyllis Diller Show" ... as well as a variety show called "The Beautiful Phyllis Diller Show." She was also a regular on "Laugh In."
She also posed for Playboy -- but the pics were never published.
Diller remained spunky to the very end, famously appearing in the 2005 movie "The Aristocrats," telling an x-rated joke ... better than comics half her age.
Joan Rivers recently appeared on "Watch What Happens Live" and said, Diller "broke the way for every woman comedian.”
