Jimmy O'Neal (born 1967) is an American painter known for large-scale installations of abstract reflective paintings. His work is often experimental, interactive, and inclusive of other media, and is sometimes derived from technological innovations such as an EEG machine and a cymascope. In 1995, he collaborated with fellow students at Savannah College of Art and Design (SCAD) to create the world's largest painting. The painting was the size of two football fields, and was included in the Guinness Book of World Records with credit to the group under the name "Southern Arts Revival."
