June Brown, who plays EastEnders stalwart Dot Branning, said it was a "pleasure" to work with the "very generous" Anna Wing, who died aged 98.
Ms Brown, who first appeared in the soap in July 1985, said: "She was a very generous woman in many ways and an excellent actress who made a script her own, lifting the character off the page and made it quite different from what you'd have expected.
"Anna always thought well of everyone and she loved and enjoyed her children and grandchildren.
"I was very fond of her indeed and will remember Anna with great affection always".
