Henry Joseph Kalis (March 2, 1937 – September 12, 2018) was an American politician who was a member of the Minnesota House of Representatives, representing southern Minnesota. First elected in 1974, Kalis was reelected every two years until he opted not to seek reelection in 2002. A Democrat, he represented the old Districts 30A and 29B and, later, 26B, which included all or portions of Blue Earth, Faribault, Freeborn, Martin and Waseca counties, changing somewhat through redistricting in 1980 and 1990. He was, along with senators Dennis Frederickson, Earl Renneke and Jim Vickerman, and representatives Gilbert Esau and Wendell Erickson, one of the longest-serving legislators from southern Minnesota in the state's history.
