Slidell Little Theatre has enchanted audiences in St. Tammany Parish since 1963.  It was founded by volunteers who recognized the need for live theatre on the Northshore.  Over the years, it has produced over 500 Main Stage shows.  Volunteers from all walks of life unite to build sets, design costumes, choreograph, and act in theatrical productions which brings music, drama, and laughter to the Northshore.

Before finding a home at 2024 Nellie Drive, next to the Fremaux Town Center, SLT performances were held at high school gyms, the city auditorium and a remodeled church.  Today, SLT's state-of-the-art facility houses two stages, the Main Stage and the Allen L. Little Stage.
