Aubin-Edmond Arsenault (28 July 1870 – 29 April 1968) was a Prince Edward Island politician.

His father, Joseph-Octave Arsenault, was a provincial politician and the first Acadian from PEI to be named to the Senate of Canada.

When Mathieson left politics for a judicial appointment in 1917, Arsenault succeeded him becoming the first Acadian to be premier in any province.

Arsenault's government repealed legislation to restrict automobile travel on the island to specific days and routes.

His government was defeated in the 1919 election, and he served as leader of the opposition until 1921 when he was appointed to the Supreme Court of Prince Edward Island.
