The Treaty on the Prohibition of Nuclear Weapons (TPNW) entered into force on 22 January 2021. Article 8, paragraph 2, of the Treaty specifies that "the first meeting of States Parties shall be convened by the Secretary- General of the United Nations within one year of the entry into force of this Treaty."

Originally scheduled to be held in January 2022, States Parties subsequently decided to hold the Meeting from 21 to 23 June 2022 at the Austria Center Vienna. On 4 April 2022, the Secretary-General of the United Nations circulated a note verbale convening the Meeting of States Parties and inviting States not party to the TPNW to attend the Meeting as observers (available in English, Français & Español).
