Her nephew George Woolf says Paton died Thursday, May 26 in Oakland, California, where she had been in hospice care after a recent heart attack.
Paton was best known for her portrayal of Mrs. Lancaster, the kindly, elderly, small-town innkeeper who played host to Murray on his never-ending day in 1993's Groundhog Day.
She had 91 film and television credits, nearly all of them after she was in her late 50s.
In 1989, she had a 6-episode run as Harriet Anderson on CBS primetime soap opera Falcon Crest. Her other TV credits included Grey's Anatomy, ER, L.A. Law and NYPD Blue.
Before that she had a long stage career based mostly in the San Francisco Bay Area, and founded a theater in Berkeley. She most recently appeared in a 2012 run of "Harvey" on Broadway.
