The 1890 Wyoming gubernatorial election was held on September 11, 1890, as the first gubernatorial election for the newly admitted state of Wyoming. Incumbent Territorial Governor Francis E. Warren ran for re-election as the Republican nominee against former Territorial Governor George W. Baxter, the Democratic nominee. Warren defeated Baxter by a decisive margin and became the first popularly elected Governor of Wyoming.
However, shortly after Warren's term began as governor, he was elected to the U.S. Senate by the newly constituted state legislature, and he resigned on November 24, 1890. Accordingly, Secretary of State Amos W. Barber became governor, and a special gubernatorial election was held in 1892.
