Heading into the election, the incumbent was Chris Murphy (Democrat), who was first elected in 2012.

A primary election is an election in which registered voters select a candidate whom they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. Connecticut utilizes a closed primary system, in which only registered party members may vote in a party's primary. However, Connecticut state law allows parties to decide whether unaffiliated voters can vote in their primary before each election.[2][3][4]

For information about which offices are nominated via primary election, see this article.

This page focuses on Connecticut's United States Senate Democratic primary. For more in-depth information on the state's Republican primary and the general election, see the following pages:
