The Tripartite Treaty is an agreement between the United Federation of Planets, the Klingon Empire, and the Romulan Star Empire, negotiated by Admiral Reto Megelis at Union shortly after opening Starbase 911.

The treaty granted the three Great Powers (mostly) free access to Union Gateway. After the Omega Crisis of 2383, the Federation suspended Klingon rights under the treaty indefinitely, and the Tripartite Treaty was superseded by the highly restrictive Treaty of Union. As of 2386, Klingon rights to the Gateway have not been restored.
