Mark Alan Ballinger (January 31, 1949 – June 13, 2014) was an American Major League Baseball pitcher who appeared in 18 games, all in relief, for the 1971 Cleveland Indians.

In 1971, he spent the season with the Jacksonville Suns, and went 5–10 with a 2.91 ERA before being promoted to the major league squad.

Ballinger worked in 34⅔ innings during his two-month-long MLB career, giving up 30 hits and 13 bases on balls, while striking out 25.

Ballinger earned his only victory on August 28, 1971, with a stellar, four-inning relief appearance against the Minnesota Twins at Cleveland Stadium, allowing no hits and only one base on balls (to future Hall of Famer Rod Carew) and striking out three as the Indians rallied to win, 9–8, on a three-run home run by Vada Pinson.

His minor league career lasted all or parts of 12 seasons; he appeared in 260 games and won 54 of 115 decisions.
