Knudt Olson Heimdal (October 19, 1830 – December 15, 1887) was a farmer and local politician from Deerfield, Wisconsin who served one term as a member of the Wisconsin State Assembly.
Born October 18, 1830, in Norway, he received a public school education before emigrating to Wisconsin with his parents in 1844.
In 1869, he was the Democratic nominee for the Assembly's 2nd Dane County district (the Towns of Bristol, Burke, Deerfield, Medina, Sun Prairie, Vienna, Westport, Windsor, and York), but lost to former state senator Willard H. Chandler with 690 votes to Chandler's 734.
In 1870 he ran again and won, with 858 votes against 751 for Republican Robert B. Sanderson (Chandler was not a candidate).
