Louis Kossuth Church (December 11, 1846 – November 23, 1897) was an American politician who was a New York Supreme Court justice, a member of the New York Legislature, and the ninth and penultimate Governor of Dakota Territory, serving from 1887 to 1889.

[3] In 1885, President Cleveland appointed Church as a justice of the Dakota Territorial Supreme Court for its Third District, replacing Seward Smith, whose mental health had come into question.

In spite of his integrity, Church became very unpopular as governor because of his opposition to separate statehood.

When Benjamin Harrison defeated Cleveland as president, Church became a lame duck who was generally ignored by the territorial legislature.

After leaving office, Louis Church returned to practicing law, first in Huron and then in Everett, Washington.
