Creators Laurence Marks and Maurice Gran say: "We're thrilled that a nation is still in love with Sharon, Tracey and Dorien and delighted that ITV loves them too and have asked us to write what will be the twelfth series of Birds Of A Feather. We can promise more feisty fun with the Essex girls."
The series focuses on sisters Tracey and Sharon, whose husbands were jailed back in 1989 for armed bank robbery, and their man-eating next-door neighbour, Dorien.
With their no-good husbands now long a thing of the past, the current ITV series see Tracey, Sharon and Dorien living together, alongside Tracey's sons, Garth and Travis.
Jon Rolph, executive producer and managing director of production company Retort, added: "We're delighted the Birds will be back again on ITV for more adventures. It's a brilliant team and a privilege to be working on one of Britain's most enduring and best loved comedies."
The new series is expected to be broadcast early in 2016.
