Frank Elmer Huelsman (June 5, 1874 – June 9, 1959) was an American professional baseball left fielder, who played in Major League Baseball (MLB) for the St. Louis Browns (NL), Chicago White Sox, Detroit Tigers, St. Louis Browns (AL), and Washington Senators.

In January 1905, the Boston Americans obtained outfielder George Stone from the Senators.

Then, the Browns reclaimed Huelsman from Washington, where he had been on loan, and sent him along with outfielder Jesse Burkett to Boston in exchange for Stone.

In a three-season career, Huelsman was a .258 hitter with five home runs and 97 RBI in 235 games.

While playing for the Salt Lake City Skyscrapers in the Class D Union Association, Huelsman won two Triple Crowns between 1911 and 1913, narrowly missing a third Triple Crown in 1912 by .002 points in batting average.
