St Michael's Mount is a tidal island in Mount's Bay, Cornwall, United Kingdom. The island is a civil parish and is linked to the town of Marazion by a man-made causeway of granite setts, passable between mid-tide and low water. It is managed by the National Trust, and the castle and chapel have been the home of the St Aubyn family since approximately 1650.

Historically, St Michael's Mount was a Cornish counterpart of Mont-Saint-Michel in Normandy, France (with which it shares the same tidal island characteristics and the same conical shape, though it is much smaller, at 57 acres [23 ha], than Mont St Michel which covers 247 acres [100 ha])

St Michael's Mount may have been the site of a monastery from the 8th to the early 11th centuries. Edward the Confessor gifted the site to the Benedictine order of Mont Saint-Michel and it was a priory of that abbey until the dissolution of the alien houses as a side-effect of the war in France by Henry V. Subsequently it ceased to be a priory, but was reduced to being a secular chapel which was given to the Abbess and Convent of Syon at Isleworth, Middlesex, in 1424. Thus ended its association with Mont St Michel and any connection with Looe Island (dedicated to the Archangel Michael). It was a destination for pilgrims, whose devotions were encouraged by an indulgence granted by Pope Gregory in the 11th century. The earliest buildings on the summit, including a castle, date to the 12th century.

Sir Henry de la Pomeroy captured the Mount in 1193, on behalf of Prince John, in the reign of King Richard I, the leader of the previous occupants having 'died of fright' upon learning rumours of Richard's release from captivity. The monastic buildings were built during the 12th century. 

John de Vere, 13th Earl of Oxford, seized and held it during a siege of 23 weeks against 6,000 of Edward IV's troops in 1473–74. Perkin Warbeck, a pretender to the English throne, occupied the Mount in 1497. Sir Humphrey Arundell, Governor of St Michael's Mount, led the Prayer Book Rebellion of 1549. During the reign of Queen Elizabeth I, it was given to Robert Cecil, Earl of Salisbury, by whose son it was sold to Sir Francis Bassett. During the Civil War, Sir Arthur Bassett, brother of Sir Francis, held the Mount against the Parliament until July 1646.

The Mount was sold in 1659 to Colonel John St Aubyn. As of 2021 his descendants, the Lords St Levan, remain seated at St Michael's Mount.

By 1811, there were 53 houses and four streets. The pier was extended in 1821 and the population peaked in the same year, when the island had 221 people. There were three schools, a Wesleyan chapel, and three public houses, mostly used by visiting sailors. Following major improvements to nearby Penzance harbour, and the extension of the railway to Penzance in 1852, the village went into decline, and many of the houses and other buildings were demolished.

During the 18th and 19th centuries, the structure of the castle was romanticised. 

A short, underground narrow gauge railway was constructed in about 1900. It was used to bring goods up to the castle and take away rubbish. In 2018, the tramway was reported as being "still in regular use, perhaps not every day", and is not open to the general public, although a small stretch is visible at the harbour. It is Britain's last functionally operational 4 ft 6 in (1,372 mm) railway

St Michael's Mount is one of 43 unbridged tidal islands that one can walk to from mainland Britain. Part of the island was designated as a Site of Special Scientific Interest in 1995 for its geology.

The mount has featured in a number of films, including the 1979 film Dracula, where it was prominently featured as the exterior of Castle Dracula. It appeared in the 1983 James Bond film Never Say Never Again, as two guided missiles armed with nuclear warheads fly over the English countryside and out to sea, passing directly over St Michael's Mount. In the 2003 film Johnny English it was used as the exterior of the character Pascal Sauvage's French chateau. In 2012 it was a filming location for the fantasy adventure movie Mariah Mundi and the Midas Box, and in 2021 for the Game of Thrones prequel series House of the Dragon.

Porthleven is the most southerly port in Great Britain, it was a harbour of refuge when this part of the Cornish coastline was infamous for wrecks in the days of sail. Porthleven's most recognisable building is the Bickford-Smith Institute next to the pier and harbour entrance. It was built on the site of the old Fisherman's Arms and was opened on 16 December 1884. The clock tower on the west corner is 70 feet (21 m) high. The Institute was grade II listed on 18 March 1991 and currently houses the town council and a snooker club. It featured (along with various other scenes from the town) as the incident room in an episode of the TV detective series Wycliffe. A picture of the building against a large breaking wave sometimes appears in the background of BBC UK weather forecasts, particularly when windy conditions and rough seas are expected.
