Port Barre (BAH-ree) is a town in St. Landry Parish, Louisiana, United States.

In 1733, the semi-nomadic Opelousas Indians petitioned the French colonial government to send traders to their district.

In 1760, a couple of coureurs des bois set up a trading post at a landing where the bayous meet.

That same year, he sold Charles Barre a large parcel of land, including the site of the first trading post.

The Barres settled in Pointe Coupee, Louisiana, where they met the Nezat family (Pierre Nezat coming from Saint Domingue), and the Provost family (Nicolas Provost coming from Paris via Fort de Chartres, in the Illinois Country).

In 1765 he bought a large parcel of land, including the site of the first trading post, from Jacques Courtableau.

In 1820, Charles Alex Barre purchased additional acres along the bank of the bayou from Sieur Jacques Guillaume Courtableau.

On July 13, 1898, the village of Port Barre was officially incorporated by Act of Proclamation of Louisiana Governor Jared Y. Sanders, Sr.[3] Port Barre is located at the confluence of Bayou Courtableau and Bayou Teche, 8 miles east of Opelousas and 52 miles west of Baton Rouge via U.S. Highway 190.

According to the United States Census Bureau, the town has a total area of 1.1 square miles (2.8 km2), all land.

Port Barre hosts an annual "Cracklin' Festival," recognized by the state of Louisiana, on the second weekend in November.
