The ambassador of the United Kingdom to Spain is the United Kingdom's foremost diplomatic representative in the Kingdom of Spain, and in charge of the UK's diplomatic mission in Spain. The official title is His Britannic Majesty's Ambassador to the Kingdom of Spain.

The British ambassador to Spain is also non-resident ambassador to the Principality of Andorra.

In 1822, the foreign secretary at that time, George Canning, downgraded the embassy to a mission, and the head of mission from an ambassador to an envoy extraordinary and minister plenipotentiary, to reflect Spain's decreased importance on the world stage. The mission in Madrid was upgraded to a full embassy once more on 9 December 1887.Chris Cook and Brendan Keith, British Historical Facts 1830-1900, Macmillan 1975, page 168
