The flag of Saint Helena consists of a Blue Ensign defaced with the shield from the British overseas territory's coat of arms.

[4] Although this change was publicised in the island's government gazette in January of that year,[5] authorisation was only granted by the Admiralty a decade later in 1994.

[9][10] Minor updates were made to the shield (and, by extension, the flag of Saint Helena) in April 2019, amid concerns that the illustration of the wirebird had become misrepresented.

It was part of an effort by Lindsay Hoyle, the Speaker of the House of Commons at the time, to observe the ceremonial days of overseas territories.

[6][12] The Blue Ensign is also used on the flags of eight of the thirteen other British Overseas Territories, with their coats of arms in the fly being the lone distinguishing feature between them.
