A Buffalo wing in American cuisine is an unbreaded chicken wing section (flat or drumette) that is generally deep-fried and then coated or dipped in a sauce consisting of a vinegar-based cayenne pepper hot sauce and melted butter prior to serving. They are traditionally served hot, along with celery sticks and carrot sticks with blue cheese dressing or, primarily outside of New York, ranch dressing for dipping. Buffalo wings are often called simply "wings" or "chicken wings".

There are several different claims about the invention of Buffalo wings. One of the claims is that Buffalo wings were first prepared at the Anchor Bar in Buffalo, New York, by Teressa Bellissimo, who owned the bar with husband Frank in 1964. At the time, chicken wings were inexpensive and undesirable, primarily being used for stock or soup.

In 1977, the city of Buffalo issued an official proclamation celebrating Anchor Bar co-owner Frank Bellissimo and declared July 29, 1977 to be Chicken Wing Day. Throughout the 1970s and 1980s Buffalo wings gained in popularity as a bar food and appetizer across the United States and Canada.
