David Howard Senjem ( SEN-jəm; born December 20, 1942) is an American politician currently serving on the Olmsted County Board of Commissioners. He is a former member of the Minnesota Senate, serving in that body from 2003 to 2023. He led the Republican caucus as majority leader from 2011 to 2013. A moderate Republican, Senjem has crossed party lines on many occasions, notably environmental policy and women's issues. He represented District 25, which at the time included portions of Dodge and Olmsted counties in the southeastern part of the state. Much of the northern half of Rochester was in his district. In April 2022, Senjem announced that he would not seek reelection to the Minnesota Senate, and later announced that he would instead run for Olmsted County Commissioner for District 2.
