Mossville is a small, predominantly African American community on the outskirts of Lake Charles in Calcasieu Parish, Louisiana, United States. It is part of the Lake Charles Metropolitan Statistical Area.
The community is featured in the 2002 documentary film Blue Vinyl, which focuses on the health effects of nearby polyvinyl chloride factories on community members. The film features footage of the Louisiana Bucket Brigade collecting air samples to determine the toxicity of the community's air. Most of the homes that were located closest to the refinery have now been either moved to other locations or torn down.
