Ross John Powell (January 24, 1968 – October 25, 2017) was an American Major League Baseball pitcher who played for the Cincinnati Reds, Houston Astros and Pittsburgh Pirates over parts of three seasons (1993–95).

He was called up by the Reds at the end of his fifth professional season and debuted on September 5, 1993, against the Philadelphia Phillies, when he threw two innings of one-hit relief.

That MLB season was curtailed by a players' strike on August 12, one day after Powell, pitching against the San Diego Padres, surrendered the earned run.

Powell made seven relief appearances for Houston between April 27 and May 13, but was treated harshly, allowing ten hits, eight bases on balls and nine earned runs in five innings pitched.

Two decades after leaving baseball, Powell, 49, who had opened a lawn-care company, was found dead of carbon monoxide poisoning in his business's van in Lucas, Texas, a suburb of Dallas–Fort Worth.
