George M. Borg (December 4, 1934 - September 7, 1971) was a Republican member of the Wisconsin State Assembly and the Wisconsin State Senate.
Borg was born in Colorado Springs, Colorado. He was an heir to the Borg-Warner fortune. His grandfather, Swedish immigrant Charles W. Borg (1861-1946), had co-founded Borg-Warner. He moved to Wisconsin in 1935 and attended the University of Wisconsin–Madison. He subsequently served in the United States Army.
Borg became an alderman in Delavan, Wisconsin. He served three terms in the Assembly before challenging three-term incumbent Peter P. Carr for the Republican Senate nomination in 1966 after the district was changed by a redistricting. He unseated Carr in a three-way primary election race, and won the general election in a district of which the Milwaukee Journal said, "Democrats are as scarce as palm trees"; but resigned from the Senate on August 9, 1967. He had been reported as planning to challenge Democrat Lynn E. Stalbaum for his Congress seat; instead, the seat was reclaimed by Henry C. Schadeberg, whom Stalbaum had defeated two years earlier.
Borg died in 1971 as a result of injuries sustained in a motorcycle accident in Lake Geneva, Wisconsin. He had three children.
