This page focuses on the Democratic primaries that will take place in Maine on June 9, 2026.

A primary election is an election in which registered voters select a candidate that 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. Maine utilizes a semi-closed primary process, in which both registered party members and unaffiliated voters may participate. Unaffiliated voters may vote in one partisan primary of their choosing in each election. Affiliated voters must change enrollment at least 15 days prior to the primary to vote in a different party's primary.

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