In 1699, the first French settlers arrived at the mouth of the Mississippi, building a fort they dubbed La Balize. As more settlers arrived and trade on the river increased, La Balize, which means ‘seamark,’ became home to the river pilots and their families. The name Plaquemines is derived from the Atakapi word piakimin, meaning ‘persimmon.’ The French established a military installation on the river and named it Plaquemines because the area was surrounded by persimmon trees.

Plaquemines Parish was established in 1807, and the current seat is Pointe á la Hache.
