J. Wellington Wimpy, generally referred to as Wimpy, is one of the characters in the long-running comic strip Popeye, created by E. C. Segar and originally called Thimble Theatre. Wimpy was one of the dominant characters in the newspaper strip, but when Popeye was adapted as an animated cartoon series by Fleischer Studios, Wimpy became a minor character. Dave Fleischer said that the character in the Segar strip was "too intellectual" to be used in film cartoons. Wimpy did appear in Robert Altman's 1980 live-action musical film Popeye, played by veteran character actor Paul Dooley.

Wimpy is Popeye's friend. In the cartoons he mainly plays the role of the "straight man" to Popeye's outbursts and wild antics. Wimpy is soft-spoken, very intelligent, and well educated, but also cowardly, very lazy, overly parsimonious and an utter glutton. He is also something of a scam artist and, especially in the newspaper.
