The list of parties to the Convention on Certain Conventional Weapons encompasses the states who have signed and ratified or acceded to the international agreement prohibiting or restricting the use of certain conventional weapons which may be deemed to be excessively injurious or have indiscriminate effects.

On April 10, 1981, the Convention on Certain Conventional Weapons (CCWC) was opened for signature. Mexico became the first state to deposit the treaty on February 11, 1982. The treaty came into force on December 2, 1983. Since April 10, 1982, states that did not sign the treaty can now only accede to it. The instrument of ratification, accession, or succession is deposited with the Secretary-General of the United Nations

As of September 2023, 127 states have ratified or acceded to the treaty, the most recent being Singapore on September 21, 2023. Four states have signed but not ratified the treaty.
