Lynn M. Luker (born August 20, 1953) is an American politician who served in the Idaho House of Representatives from 2006 to 2018, representing District 15 in the A seat.
Luker was born in Idaho Falls, Idaho and graduated from Lompoc High School. He earned his bachelor's degree in political science from University of California, Berkeley and Juris Doctor from University of Idaho College of Law.
In 2004, Luker challenged 12-year incumbent Representative Max Black in the Republican primary, losing by 70 votes.
