Étienne Perier or Étienne de Perier (1686 – 1766), also known as Perier the Elder (French: Perier l'Aîné), was a French naval officer and governor of French Louisiana from 1726 to 1733. His time as governor included some notable achievements, including the construction of the first levee along the Mississippi River in 1727. In response to the Natchez Revolt, he attempted to completely destroy the Natchez people, which increased Native American hostility toward the French in the territory. Because he failed to secure the safety of the colony, Perier was recalled as governor in March 1733. He later distinguished himself as a naval officer and privateer, including during the capture of HMS Northumberland in 1744.
