W. Todd Akin (born July 5, 1947), American politician, has been a Republican member of the United States House of Representatives since 2001, representing Missouri's 2nd congressional district (map). The district includes the western and northwestern suburbs of St. Louis.

Born in New York City, Akin later moved to St. Louis, and attended John Burroughs School. After graduating, he attended the Worcester Polytechnic Institute, in Worcester, Massachusetts, where he earned a degree in Management Engineering, and in 1984, he earned a Master of Divinity degree at Covenant Theological Seminary in St. Louis. From 1972 to 1980, he served in the Missouri National Guard. After his military career, he took up work at IBM as an engineer, and he later became a manager at Laclede Steel. Akin was elected to the Missouri House of Representatives representing western St. Louis County in 1988. He was re-elected five times.

In 2000, US Representative Jim Talent did not seek re-election because he was running for Governor of Missouri. Akin won a closely contested Republican primary election to replace Talent, defeating former St. Louis County Executive Gene McNary and Missouri State Senator Franc Flotron. He defeated Missouri Senator Ted House in the general election, winning 55% of the vote.
