Mark G. Lipscomb, Jr. (September 1, 1935 - ) is an American lawyer, former postal clerk and politician from Milwaukee, Wisconsin who served four terms as a Democratic member of the Wisconsin State Assembly and one partial term in the Wisconsin State Senate.
Lipscomb was born in Milwaukee, September 1, 1935. He graduated from Marquette University High School, and earned a B.S. in business administration from Marquette University in 1957 (he was a track athlete, specializing in the half-mile run and president of the track club). He served in the Marines from 1957 to 1960, then got a LL.B. from Marquette's law school in 1964. In addition to his law practice, he has worked as a postal clerk, and belonged to the United Federation of Postal Clerks.
In 1964 Lipscomb ran for the Assembly's first Milwaukee County District (the 1st Ward of the City of Milwaukee, and the 6th Ward of the City of Glendale). After unseating incumbent Stan Pelecky with a plurality in a six-way Democratic primary election (36.9% to Pelecky's 29.6%), he was unopposed in the general election. He was assigned to the standing committees on finance and third reading (chairing the latter), and to Wisconsin Legislative Council special joint committees to study Wisconsin's civil service and Milwaukee County's children's court system (chairing the latter). He was unopposed in the 1966 primary, and beat his Republican opponent Herbert Schollmeyer 7054 to 2086. After an easy win in the 1970 primary, he again defeated Schollmeyer in the general election, by a larger margin.
