Doris Roberts Dead at 90

Doris Roberts, the beloved mom from "Everybody Loves Raymond," has died ... TMZ has learned.

We're told Doris passed away Sunday at home in L.A.

She won 5 Emmy awards, 4 of them for 'Raymond.' She's also starred in tons of other TV shows and movies, like "National Lampoon's Christmas Vacation" and "Grandma's Boy."

She's survived by her son, Michael Cannata Jr., who she had with her first husband. Doris' second husband, William Goyen, died in 1983.

Doris was 90 years old.

We last saw her about a month ago where we frequently got her -- going to the movies at the ArcLight in Hollywood. Doris said she wasn't feeling great, but she was as witty as ever.
