The lieutenant governor of Prince Edward Island is the representative in Prince Edward Island of the monarch, who operates distinctly within the province but is also shared equally with the ten other jurisdictions of Canada, as well as the other Commonwealth realms and any subdivisions thereof, and resides predominantly in his oldest realm, the United Kingdom. The lieutenant governor of Prince Edward Island is appointed in the same manner as the other provincial viceroys in Canada and is similarly tasked with carrying out most of the monarch's constitutional and ceremonial duties.

The island has several nicknames: "Garden of the Gulf", "Birthplace of Confederation" and "Cradle of Confederation". Its capital and largest city is Charlottetown.
