Missouri's third congressional district is in the eastern and central portion of the state. It stretches from the southern part ofColumbia (including theUniversity of Missouri) and the state capital ofJefferson City in the west toSt. Charles County (including the large suburbs ofSt. Charles,St. Peters andWentzville) and westernJefferson County in the east. The district took its current form in 2023, whenCooper and parts ofBoone counties were added to the district, whileFranklin and most ofWarren counties were instead drawn into the2nd district, and much ofLincoln County moved to the6th district. Its current representative is RepublicanBob Onder.
The Columbia portion in the 3rd includes theUniversity of Missouri. The northern portion of the city is in the4th district.
From 1953 to 2013, the 3rd had been located in the southern portion of the St. Louis area, including the southern third of St. Louis City, and had a dramatically different political history from the current 3rd. Its best-known congressman isDick Gephardt, who represented the district for 28 years until his retirement from Congress.
Following a dramatic drop in the population of St. Louis in the2010 United States census, Missouri lost a congressional seat effective in 2013. Redistricting maps indicated that the 3rd district would be dismantled. The 3rd's home base in St. Louis would be absorbed byMissouri's 1st congressional district. Much of the district outside the St. Louis area would be drawn into the8th district. Meanwhile, the new 3rd included most of the territory currently in the9th district, which was dissolved.[3]
