Solomon Gilman Comstock (May 9, 1842 – June 3, 1933) was an American attorney and politician who served as a member of the United States House of Representatives for Minnesota's 5th congressional district from 1889 to 1891.

He moved to Nebraska in 1869 and settled in Omaha, where he was admitted to the bar the same year and commenced practice.

When Clay County government was established in April 1872 in response to the killing of Slim Jim Shumway by Shang Stanton, Comstock was the only man in town with a law degree.

[2][3] After resuming his real estate business in Moorhead, Comstock also engaged in manufacturing farm implements in 1893.

He was a member of the state normal school board from 1897 to 1905, and retired from business pursuits and resided in Moorhead, Minnesota, until his death on June 3, 1933.
