The most recent amendment to the United States Constitution that was officially passed is the 27th Amendment. It was originally proposed in 1789 and was not ratified until 1992. Since then, no new amendments have been fully ratified and added to the Constitution as of 2025.
Recent proposed amendments have been introduced in the 119th Congress, but none have completed the ratification process so far this year. Therefore, the 27th Amendment remains the most recent amendment passed.
