The accession of the United Kingdom to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) has been on the current agenda for the enlargement of the CPTPP since 2 June 2021, when the CPTPP Commission decided to move forward with the application of the United Kingdom as an aspirant economy. The United Kingdom officially applied for CPTPP membership on 1 February 2021. Accession negotiations between the UK and the 11 current CPTPP members negotiations were concluded on 31 March 2023. The UK formally signed the accession protocol on 16 July 2023. The UK and at least 6 of the 11 existing member nations will need to ratify the accession protocol before it takes effect. The UK Government expected the entry into force to take place in the second half of 2024. On 29 August 2024, the UK government announced the agreement is expected to enter into force on 15 December 2024, after securing the final ratification required for membership.

The UK became the first non-original member and European country to join CPTPP. Following the UK's accession application, seven countries have applied to join CPTPP: China, Costa Rica, Ecuador, Indonesia, Taiwan, Ukraine, and Uruguay.
