Gerald Wesley Moran is an American lawyer and politician who is the senior United States senator from Kansas, a seat he has held since 2011. A member of the Republican Party, he was chair of the National Republican Senatorial Committee for the 113th U.S. Congress, during which he led successful Republican efforts in the 2014 election, producing the first Republican Senate majority since 2006. Previously, he was a member of the United States House of Representatives, representing Kansas's 1st congressional district.

Since Kansas became a U.S. state in 1861, it has sent congressional delegations to the United States Senate and United States House of Representatives. Each state elects two senators to serve for six years, and members of the House to two-year terms. Before becoming a state, the Kansas Territory elected a non-voting delegate at-large to Congress from 1854 to 1861.
