Antoinette Perry, is a Canadian former schoolteacher and the 29th lieutenant governor of Prince Edward Island since 2017, acting as the province's viceregal representative of King Charles III of Canada. She was appointed on September 14, 2017, by Governor General David Johnston on the constitutional advice of Prime Minister Justin Trudeau, and was sworn in on October 20, 2017, succeeding H. Frank Lewis. Perry's swearing in ceremony took place in Tignish, Prince Edward Island, marking the first time a PEI lieutenant governor was sworn in outside of the province's capital, Charlottetown.

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.
