His Majesty's Naval Base, Portsmouth (HMNB Portsmouth) is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Clyde and HMNB Devonport). Portsmouth Naval Base is part of the city of Portsmouth; it is located on the eastern shore of Portsmouth Harbour, north of the Solent and the Isle of Wight. For centuries it was officially known as HM Dockyard, Portsmouth: as a Royal Dockyard, Portsmouth functioned primarily as a state-owned facility for building, repairing and maintaining warships; for a time it was the largest industrial site in the world.From the 1970s, the term 'Naval Base' began to be used for Portsmouth (and other Royal Dockyards), acknowledging a greater focus on personnel and support elements alongside the traditional industrial emphases. In 1984 Portsmouth's Royal Dockyard function was significantly downsized and downgraded, and was formally renamed the 'Fleet Maintenance and Repair Organisation' (FMRO). The FMRO was privatised in 1998; in 2002, shipbuilding (which had not taken place on site since the late 1960s) resumed in the form of block construction, but this again ceased in 2014.Today, Portsmouth is the home base for two-thirds of the Royal Navy surface fleet, including the two aircraft carriers, HMS Queen Elizabeth and HMS Prince of Wales. Naval logistics, accommodation and messing are provided on site, with personnel support functions (e.g. medical and dental; education; pastoral and welfare) provided by Defence Equipment and Support. Other functions and departments, e.g. Navy Command Headquarters support staff, are also accommodated within the Naval Base. The base is additionally home to a number of commercial shore activities, including the ship repair and maintenance facility operated by BAE Systems Maritime. The base is the oldest in the Royal Navy, and it has been an important part of the Senior Service's history and the defence of the British Isles for centuries. It is home to one of the oldest surviving drydocks in the world. The former Block Mills are of international significance, having been the first factory in the world to employ steam-powered machine tools for mass production. The Royal Naval Museum has been on the site since 1911. In 1985 a partnership between the Ministry of Defence and Portsmouth City Council created the Portsmouth Naval Base Property Trust to manage part of the historic south-west corner of the Naval Base, under a 99-year lease, as an heritage area, the Portsmouth Historic Dockyard. It allows members of the public to visit important maritime attractions such as Mary Rose, HMS Victory, HMS Warrior and the National Museum of the Royal Navy.

St Ann's Church is an Anglican chapel within His Majesty's Naval Base Portsmouth. It is regarded as the spiritual home of the Royal Navy, and contains numerous memorials to men lost at sea.The original church was built in 1704, on the site of what is now Admiralty House. The present church was opened in 1786, and is built in red brick in Flemish bond. It was possibly designed by Marquand, a Navy Board surveyor, working under Samuel Wyatt at Admiralty House. The contractors were Thomas Parlby & Sons. The church suffered some bomb damage in May 1941, and was restored in 1955–6. As the oldest surviving chapel in a navy yard, it was Grade II listed on 25 September 1972.In October 2012, the church held ceremonies marking the 30th anniversary of the Falklands War, attended by HRH The Princess Royal. As of 2015 the current chaplain is Revd. James Francis, RN. The HMS Royal Oak Association holds an Act of Remembrance annually at the church on the Saturday nearest to 13 October, the date of the sinking of the battleship HMS Royal Oak (08) at Scapa Flow in 1939. At the service on 9 October 2019, eighty years after the ship was torpedoed, a memorial stone was unveiled in the church by HRH The Princess Royal. Although the last survivor died in 2016, some one hundred and fifty relatives and descendants of the crew attended.

The Portsmouth Block Mills form part of the Portsmouth Dockyard at Portsmouth, Hampshire, England, and were built during the Napoleonic Wars to supply the British Royal Navy with pulley blocks. They started the age of mass-production using all-metal machine tools and are regarded as one of the seminal buildings of the British Industrial Revolution. They are also the site of the first stationary steam engines used by the Admiralty.Since 2003 English Heritage has been undertaking a detailed survey of the buildings and the records relating to the machines.
