Jeffrey William Colyer (born June 3, 1960) is an American surgeon who served as the 47th governor of Kansas from January 31, 2018 to January 14, 2019.
A Republican, he served as the 49th lieutenant governor of Kansas from 2011 to 2018, as a member of the Kansas Senate from 2009 to 2011, and in the Kansas House of Representatives from 2007 to 2009.
Colyer became governor of Kansas when Governor Sam Brownback resigned to take an ambassador position. Colyer ran for a full term as governor in 2018, but was narrowly defeated in the Republican primary by Kansas secretary of state Kris Kobach, who in turn lost the general election to Democratic nominee Laura Kelly.
