Adolph Olson Eberhart (June 23, 1870–December 6, 1944) was born in Sweden and became an American politician.

He was a member of the Minnesota State Senate from January, 1903 to January, 1907. He was elected Lieutenant Governor in 1906. He became the 17th Governor of Minnesota on September 21, 1909, when Governor John Albert Johnson died, and served until January 5, 1915. Eberhart was a Republican. Minnesota elected Governors and Lt. Governors on separate ballots until 1974, so it happened occasionally that the two were of different parties.
