Marcia Wallace -- who voiced Edna Krabappel on "The Simpsons" -- died last night in Los Angeles ... TMZ has learned.

Marcia's caregiver tells us ... the actress passed away at home with her family by her side. We're told she had been sick for the past few months ... but the caregiver couldn't go into specifics.

Wallace has been on TV since the 70's -- and spent 3 decades on various game show panels like "Hollywood Squares", "The $25,000 Pyramid" and "Match Game" ... as well as receptionist Carol Kester on "The Bob Newhart Show."

The actress was also a huge activist for breast cancer ... after being diagnosed with the disease in 1985.

She was 70.

How sad! I loved her on The Bob Newhart Show. RIP Marcia:(

R. I..P. Marcia. Thanks for creating a classic character.:(

How sad; 70 is too young to die. She was great as Carol the receptionist.

:rip: Marcia Wallace. I'm glad she had a second career as a voice actor on the Simpsons but she will always be Carol Kester Bondurant to me.

Sad news. May she :rip:

So sad to hear of Marcia's passing. I wonder how they will write her passing into The Simpsons?

Marcia also played Mrs. Carruthers on Full House.

RIP.
