Kim J. Gillan (born December 10, 1951), is an American politician and former Democratic Party member of the Montana Senate. She represented District 24 from 2004 to 2012. She was unable to run for reelection in 2012 due to Montana's term limits. Earlier she was a member of the Montana House of Representatives from 1996 through 2004. On June 21, 2011, she announced that she would be a candidate for the U.S. House of Representatives for the open seat in Montana's at-large congressional district that was available in the 2012 election due to incumbent Denny Rehberg's decision to run against U.S. Senator Jon Tester. Gillan was defeated by Republican businessman Steve Daines in the November 2012 general election.
