St. Martin Parish

With a population of approximately 53,000, St. Martin Parish is part of the Lafayette MSA and sits at the corridor of both Interstate 10 and U.S. Highway 90.  St. Martin Parish is the only parish to have non-contiguous parts, in that, there are three major geographical areas dividing the 740 square mile parish, including the Atchafalaya Basin, the prairie, and the Bayou Teche area, on which several major cities, including the parish seat of St. Martinville, are located.

From the Bayou Teche to the Atchafalaya Basin, St. Martin Parish is a picturesque and bountiful region.  Rich in agriculture, visitors are taken through sugar cane fields, low-lying swamp land, and rolling hills.  Majestic live oaks draped with moss are scattered along roadways, where bald cypress trees and wildlife abound.

St. Martin Parish’s central location in Acadiana and Southern Louisiana offers access to exceptional schools, healthcare, and endless recreation.  Entrepreneurs looking to take advantage of St. Martin Parish’s business-friendly environment, skilled workforce, and convenient locale near two regional airports and major roadways, are welcome to settle in to the SMEDA Business Park, near U.S. Highway 90, or Commercial Park East, located just off Interstate 10  in Breaux Bridge.  Here in St. Martin Parish, we understand that success for local businesses means success for all the community.
