Johnson Bayou is a small unincorporated community located on the Creole Nature Trail along the Gulf Coast in Cameron Parish, Louisiana, United States, and is named after Daniel Johnson, who came to the area circa 1790. The village is a barrier island spread across coastal chenieres which were formed by deltaic sedimentation by the shifting of the Mississippi River. This geologic formation, the coastal cheniere, is found only in a few locations across the globe. The population of the community was approximately 400 before Hurricanes Laura and Delta devastated the community in August and October of 2020. By September of 2021 the population had recovered to almost 300.
