The District of Columbia Voting Rights Amendment was a proposed amendment to the United States Constitution that would have given the District of Columbia full representation in the United States Congress, full representation in the Electoral College system, and full participation in the process by which the Constitution is amended. It would have also repealed the Twenty-third Amendment, which granted the District of Columbia the same number of electoral votes as that of the least populous state, but gave it no role in contingent elections.

The amendment was proposed by the U.S. Congress on August 22, 1978, and the legislatures of the 50 states were given seven years to consider it. Ratification by 38 states was necessary for the amendment to become part of the Constitution; only 16 states had ratified it when the seven-year time limit expired on August 22, 1985. This proposed constitutional amendment is the most recent one to have been sent to the states for their consideration.
