Michael Alan McGrath (October 27, 1942 – January 27, 2021) was an American politician and businessman.
He served in the United States Air Force before marrying Marsha Palmer of New Smyrna Beach, attending Daytona Beach Community College, and graduating from Stetson University in 1969 with a bachelor's degree in American Studies.
McGrath was employed by International Dairy Queen, Inc., in Bloomington, Minnesota, from 1972 to 1984, ending as a vice president.
He next worked as a business consultant and taxi driver, and was active in grassroots politics before defeating the DFL incumbent in the 1986 primary and general elections for Minnesota State Treasurer.
McGrath's longtime assistant, Carol Johnson, was elected as the final State Treasurer of Minnesota in 1998 following passage of a constitutional amendment to abolish the office on the same ballot.
