The Admiralty was a department of the Government of the United Kingdom responsible for the command of the Royal Navy until 1964, historically under its titular head, the Lord High Admiral – one of the Great Officers of State. For much of its history, from the early 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence and its Navy Department.

Admiral Ben Key was appointed First Sea Lord in November 2021.

The Board of Admiralty (1628–1964) was established in 1628 when Charles I put the office of Lord High Admiral into commission. As that position was not always occupied, the purpose was to enable management of the day-to-day operational requirements of the Royal Navy; at that point administrative control of the navy was still the responsibility of the Navy Board, established in 1546. This system remained in place until 1832, when the Board of Admiralty became the sole authority charged with both administrative and operational control of the navy when the Navy Board was abolished. The term Admiralty has become synonymous with the command and control of the Royal Navy, partly personified in the Board of Admiralty and in the Admiralty buildings in London from where operations were in large part directed. It existed until 1964 when the office of First Lord of the Admiralty was finally abolished and the functions of the Lords Commissioners were transferred to the new Admiralty Board and the tri-service Defence Council of the United Kingdom.
