Clark MacGregor was an American politician and Republican U.S. Representative from Minnesota's 3rd Congressional District for five terms from 1961 to 1971.

Minnesota's 3rd congressional district encompasses the suburbs of Hennepin and Anoka counties to the west, south, and north of Minneapolis. The district, which is mostly suburban in character, includes a few farming communities on its far western edge and also inner-ring suburban areas on its eastern edge. The district includes the blue collar cities of Brooklyn Park and Coon Rapids to the north-east, middle-income Bloomington to the south, and higher-income Eden Prairie, Edina, Maple Grove, Plymouth, Minnetonka, and Wayzata to the west. Democrat Dean Phillips currently represents the district in the U.S. House of Representatives, after defeating incumbent Republican Erik Paulsen in the 2018 midterm elections.
