Steven Bernard Mingori (February 29, 1944 – July 10, 2008) was a left-handed relief pitcher in Major League Baseball who played for the Cleveland Indians (1970–1973) and Kansas City Royals (1973–1979).

Steve was born in Kansas City, Missouri. He was signed by the Cincinnati Reds in 1965, and spent the next five years in the Reds' minor league system. Before the 1970 season began, the Reds traded him to the Cleveland Indians for Jay Ward.

Mingori made his major league debut on August 5, 1970, and finished the season with a 1–0 win-loss record and a 2.66 earned run average (ERA) in 21 games. The following season, he pitched in 47 games until he suffered a broken jaw in an early August game, causing him to miss nearly the rest of the season. He spent another season and a half with the Indians, then was traded to the Kansas City Royals on June 8, 1973.

Steve pitched in the postseason in 1976, 1977 and 1978 for the Royals, all against the Yankees, and did not get a decision.

In a ten-season career, Steve posted a 3.03 earned run average and earned 42 saves in 385 games pitched, all but two of which came as a reliever. He died on July 10, 2008 in his hometown of Liberty, Missouri of natural causes.

Steve shared his 1971 Topps Rookie card with fellow IA player, Lou Camilli.
