Steve Chassey (born February 27, 1945, Brockton, Massachusetts), is a former driver in the CART Championship Car series. He raced in 9 seasons (1981, 1983-1989, and 1992), with 44 career starts, including the Indianapolis 500 in 1983, 1987, and 1988. He finished in the top ten 4 times, with his best finish in 5th position in 1981 at Watkins Glen International. He raced his last Indy 500 in 1988 for Gary Trout Motorsports finishing 24th.

Chassey also worked for ESPN, commentating on Thursday night "Thunder" USAC events. During a 1989 "Thunder" broadcast, Chassey and fellow announcer Larry Nuber disagreed over Rich Vogler, although Chassey stayed on ESPN until he was replaced by Larry Rice in 1991.The comment that caused all the stir was "that was the first accident that I had seen that Vogler didn't cause". After every race his sponsors would go to the production truck and demanded to see the tape and hear what was said I know from experience, Vogler caused a big crash at Terre Haute when he drove into my left rear in turn three, he tried to pass me on the outside in the grey at Michigan and spun in front of me and actually blamed me for the accident that fractured my pelvis, at Indy he tried to drive by the outside in turn three and cause a monster crash again, so I know what I am talking about.
