Robert George Wiesler (August 13, 1930 – August 10, 2014) was a pitcher in Major League Baseball who played for the New York Yankees and Washington Senators in parts of five seasons spanning 1951–1958. Listed at 6' 3", 188 lb., he was a switch-hitter and threw left-handed.

Wiesler was signed by the Yankees as an amateur free agent in 1949 out of Beaumont High School in St. Louis, Missouri. He was assigned immediately to the Independence Yankees of the Kansas–Oklahoma–Missouri League, where he posted a 12-11 record with a league-leading 240 strikeouts in 185 innings, helping his team to win the regular season pennant and the playoffs.

Wiesler gained a promotion to the Joplin Miners in 1950, and he simply dominated, going 15-7 with 11 complete games and two shutouts, while leading the Western Association with a 2.35 ERA and 277 strikeouts, en route to a league pennant and an All-Star recognition.

The strong armed lefty opened 1951 with the Kansas City Blues of the American Association, and he responded with a 10-9 mark and a 2.92 ERA in a career-high 194 innings, striking out 162 batters to claim his third strikeout title in a row. He joined the Yankees on August 3 of this year and lost two decisions in four appearances. He was then called up for military service, missing the 1952 season while serving with the United States Army during the Korean War conflict.
