Hugh Galbraitha Harrison (April 23, 1822 – August 12, 1891) was a real estate investor and banker who served as the second mayor of Minneapolis, Minnesota.

While growing up he helped his father and older brothers who were involved in the milling business before attending college at McKendree University.

[3][4] There are few details of his term — sources note his administration was "businesslike"[1] and "careful, capable and clean.

That same year Harrison and his brothers took their profits and organized the Security Bank, one of the early city's largest financial institutions.

[1][2] Harrison ran for Governor of Minnesota in the 1888 election as the Prohibition Party's candidate, but came in third place with 6.51% of the vote, losing to Republican William Rush Merriam and Democrat Eugene McLanahan Wilson.
