This page focuses on the Republican primaries that will take place in Colorado on June 30, 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.

Colorado utilizes a semi-closed primary system. According to Section 1-7-201 of the Colorado Revised Statutes, "An eligible unaffiliated elector, including a preregistrant who is eligible under section 1-2-101 (2)(c), is entitled to vote in the primary election of a major political party without affiliating with that political party."

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