The 2026 Colombian legislative elections were held on Sunday, March 8. They elected the members of both chambers of the Congress of Colombia for the 2026–2030 term, from a total of 3,144 candidates.

The Senate of Colombia held elections for 103 senators: 100 from the national constituency, two from the special indigenous constituency, and one seat reserved for the runner-up in the presidential election.

The Chamber of Representatives held elections for 183 members. Of these, 161 represent the 32 departments and the Capital District, two represent Afro-descendant communities, one represents Indigenous communities, one represents the Raizal people of San Andrés and Providencia, and one represents the international constituency. The remaining seats comprise 16 elected from the Special Transitional Peace Constituencies, a set of 16 districts covering the rural regions most affected by the Colombian armed conflict, in which only victims of the conflict or their accredited community organizations may stand as candidates; and one reserved for the running mate of the second-place ticket in the presidential election.

This was the first election in which the five seats guaranteed to the Commons party in each chamber were no longer in effect, requiring the party to compete on equal footing with the other politically registered groups. Commons lost all five seats.
