Her Majesty's Passport Office (HMPO) is an agency of the Home Office in the United Kingdom. It provides passports for British nationals worldwide and was formed on 1 April 2006 as the Identity and Passport Service (a successor to the United Kingdom Passport Agency, which was founded in 1991, although the Passport Office had also been its previous name) before being renamed HM Passport Office on 13 May 2013.

The General Register Office for England and Wales became a subsidiary of HMPO on 1 April 2008, and produces life event certificates such as birth, death, marriage and civil partnerships.

HMPO's headquarters is co-located with the Home Office at 2 Marsham Street and it has seven regional offices around the UK, in London, Glasgow, Belfast, Peterborough, Liverpool, Newport and Durham as well as an extensive nationwide interview office network as first time adult passport applicants may be required to attend an interview to verify their identity as a fraud prevention measure.
