The British Embassy Kyiv () is the British sovereign's diplomatic mission to Ukraine, representing the United Kingdom and the United Kingdom's interests. The embassy is located on Desyatynna street in the Pecherskyi District of the city, directly opposite the building of the Ministry of Foreign Affairs of Ukraine. The British Ambassador to Ukraine is Neil Crompton who was appointed in October 2025.

The United Kingdom withdrew around half of all staff in the days following 24 January 2022 amid fears of a Russian invasion, according to a statement from the Foreign Office. This followed a similar slow withdrawal of Russian embassy staff and relatives of U.S. embassy staff leaving Ukraine. On 20 April 2022, it was announced that the British Embassy in Kyiv would be reopening the following week. During 2022, 350 Royal Marines from 45 Commando supported embassy diplomats in Ukraine.
