Frank Szymanski (July 6, 1923 – April 26, 1987) was an American football player and probate judge in Wayne County, MI.

While living in Detroit, Szymanski played football at Northeastern High School and was voted to both All-City and All-State teams.

In 1943 he started at center and linebacker for all ten games of the Irish's 9–1 season, after which they were named unanimous national champions for the first time since 1930.

Szymanski served in the Navy for the beginning of the 1944 season and rejoined the team after a medical discharge for a 59–0 loss to rival Army which remains the largest defeat in Irish history.

On November 15, 1947 the Lions paid tribute to their center by celebrating "Szymanski day" at historic Briggs Stadium.

After his NFL career he practiced privately for a number of years before being appointed auditor general of Michigan by Governor G. Mennen Williams in 1956.
