William Casey Elliott[1] (February 13, 1974 – January 14, 1996) was an American stock car racing driver.

[3] By 1993, at age eighteen,[4] he was ready to move up to top level NASCAR competition; in addition to running full-time in the Slim Jim All Pro Series,[5] he formed Casey Elliott Sports with his parents and sisters to compete in the Xfinity Series with Eagle Snacks sponsorship,[6] and the team ran two races that year.

[7] Elliott planned to compete full-time in the Busch Series (later Xfinity) starting in 1994;[9] however, in December 1993, a medical examination revealed that a growth on his upper right thigh was cancerous.

He had surgery to remove it in February 1994; [10] although it was believed that the cancer had been confined to the removed tumor,[11] and Elliott initially showed improvement,[12] the cancer had already metastasized; not long afterwards Elliott required knee replacement surgery, ending his racing career.

[17] Chase Elliott, Casey Elliott's cousin, ran a tribute paint scheme on his NASCAR Monster Energy Cup Series car at Darlington Raceway in the 2018 Bojangles' Southern 500, designed to resemble the one driven by Casey.
