Although Georgia's character was popular on the hit comedy show Everybody Loves Raymond, she was best known for playing Georgette Franklin Baxter in the successful sitcom The Mary Tyler Moore Show from 1972 to 1977. The cause was undetermined, Quilty told the Times, because Engel, a Christian Scientist, did not consult doctors.
Engel's friend and executor, John Quilty, said she died on Friday, April 12, in Princeton, New Jersey, according to The Associated Press.
Engel's other acting credits included film appearances in Dr Dolittle 2, The Sweetest Thing and TV shows such as The Office and Two And A Half Men.
She was a five-time Emmy nominee, receiving two nods for the late Moore's show and three for Everybody Loves Raymond.
Engel appeared on Broadway in plays and musicals including Hello, Dolly!
Actress Valerie Bertinelli paid tribute to her Hot In Cleveland co-star on Twitter, writing: "Georgia Engel was the sweetest, kindest, dearest woman".
She recalled that a possible Everybody Loves Raymond spinoff set to include her and Fred Willard never come to fruition, which she called a great disappointment.
Engel was the daughter of a US Coast Guard admiral, and growing up she moved many times across the US.
The 70-year-old is the fourth star from the show to pass away.
