Pascal Poirier (February 15, 1852 – September 25, 1933) was a Canadian author, lawyer, and the all-time longest-serving Senator.

At an early age he wrote a book on the Origin of Acadians, a history that contradicted myths of the time.

After finishing school at the College Saint-Joseph in Memramcook during 1872, Poirier was appointed Postmaster of the Dominion Parliament at age 20.
