John Albert Niehoff (May 13, 1884 – September 8, 1974) was a second baseman in Major League Baseball who played for four clubs from the 1913 to 1918 seasons.

A native of Louisville, Colorado, Niehoff entered the majors in 1913 with the Cincinnati Reds, playing for them two years before joining the Philadelphia Phillies (1915–1917), St. Louis Cardinals (1918) and New York Giants (1918).

He was a classic line-drive hitter and steady double play partner for shortstops Buck Herzog (Reds) and Dave Bancroft (Phillies).

He also was a member of the Phillies team that lost the 1915 World Series to the Boston Red Sox.

From 1943 to 1944 Niehoff managed the South Bend Blue Sox, a team that included talented players as Bonnie Baker, Doris Barr and Dottie Schroeder (the only woman who played every season of the AAGPBL).
