This claim is unsubstantiated, although the Chick-fil-A southern-style chicken burger (served with pickles on a steamed roll), introduced in 1964[3] on March 21, may have been the first chicken burger introduced by an American fast food restaurant chain.
Other notable vendors of chicken burgers include KFC and Popeyes.

This competition has coincided with a significant rise in the prevalence of fried chicken burger on menus nationwide.
As of 2024, 47% of restaurant menus feature fried chicken sandwiches, compared to 41% for hamburgers.
