The coat of arms of Anguilla is the heraldic device consisting of a shield charged with three orange dolphins leaping over the sea.

A legislative union between the two islands was later established in 1825, despite vehement opposition from Anguillan freeholders over the arrangement of having Saint Kitts pass laws for both areas.

[5] In the run-up to the fiftieth anniversary of the Anguillian Revolution in 2017, a proposal was drawn up to augment the coat of arms with a crest and two supporters, along with the territory's motto.

[6] The design was submitted for approval in March of that year, with the College of Arms overseeing its technical aspects.

[8] The official blazon granted by the British College of Arms is as follows: Argent in base the Sea of Turquoise hue in chief three natural Dolphins embowed and leaping in a circle each tinctured Orange-Gold the Shield garnished of Gold.
