Port-de-Paix (French pronunciation: [pɔʁ də pɛ] ⓘ; Haitian Creole: Pòdepè or Pòdpè; meaning "Port of Peace") is a commune and the capital of the Nord-Ouest department of Haiti on the Atlantic coast.

[1] The city of Port-de-Paix located on a small coastal plain on the Atlantic coast of Haiti in the Tortuga Canal on the bank of Three-Rivers in an area marked by agricultural activities.

The arrondissement consists of five communes: Port-de-Paix, La Pointe des Palmistes, Bassin-Bleu, Chansolme and Tortuga.

The area around the town was given the name "Valparaíso" by Christopher Columbus after landing here in the late evening of December 6, 1492, and today still contains many attractive beaches and cave locations.

A ferry operates between the town and Tortuga island, (La Tortue), called "Gusaeni Cahini" by the Taïnos, which is situated just across the water.
