The Saint Helena pound (also called simply "pound") is the currency of the Atlantic islands of Saint Helena andAscension, which are constituents of the British overseas territory of Saint Helena, Ascension and Tristan da Cunha. It is fixed at parity with the pound sterling and is subdivided into 100 pence.

In 1984, circulation coins were first introduced in the names of St. Helena and Ascension in denominations of 1, 2, 5, 10 and 50 pence and 1 pound. From 1716, the Governor and Council of the Island of St Helena issued notes for 2½ and 5 shillings and 1 and 2 pounds. These were issued up until the late 18th century.

The next issue of notes occurred sometime after 1917. It was produced by the St Helena Currency Board in denominations of 5, 20 and 40 shillings.

In 1976, the currency board of the Government of Saint Helena began issuing 1- and 5-pound notes, followed by 50-pence and 10-pound notes in 1979. The 50 pence and 1 pound notes were withdrawn and replaced by coinciding coins in 1984, with 20-pound notes first being introduced in 1986.

In 2004, a new series of 5, 10, and 20-pound notes was introduced featuring a redesign and newer security features, produced by De La Rue Banknote and Engraving Company.
