Turner Mastin Marquett (July 19, 1831 – December 22, 1894) was a NebraskaRepublican politician best known for being the first House representative for the state.
Marquett was a member of the Nebraska Territorial assembly from 1857 to 1859, and in the Territorial council in 1860 and 1861. He ran and won as Delegate from the Territory of Nebraska to the Fortieth United States Congress, but, since Nebraska was accepted as a state in 1867, the election was voided. He ran for the at-large seat as a U.S. representative for the State of Nebraska, but, because of the exact date of admission, he was only able to serve as a representative for two days.
