William Robert Steinecke (February 7, 1907 – July 20, 1986) was an American professional baseball catcher and manager. A native of Cincinnati who attended DePaul University, Steinecke spent almost 40 years in uniform, but only four games in Major League Baseball (with the Pittsburgh Pirates).

Steinecke achieved his most sustained success in the New York–Penn League of the 1930s (now the Eastern League), batting over .300 in six different seasons. In his best campaign, for the Williamsport Grays, Steinecke batted .349 with 110 runs batted in in 132 games played. All told, he appeared in 1,907 minor league games over 21 different seasons, batting .297 with 57 home runs and 855 RBI.
Steinecke's long minor-league managerial career began in in the Class B Sally League, and from 1946 to 1964 he skippered clubs in the lower minors. He joined the Milwaukee Braves farm system in and continued with the Braves through the middle of . (As manager of the Class D McCook Braves of the Nebraska State League, he was a figure in former bonus-baby pitcher Pat Jordan's memoir, A False Spring.) He then served as a scout for the Braves and Montreal Expos. Steinecke died at age 79 in Saint Augustine, Florida.
