Caernarvon is an unincorporated community in St. Bernard Parish, Louisiana, United States. The name of the community is from a plantation originally located here. The plantation's name is widely believed to be from a similarly named town and castle in Wales. Names of antebellum plantations in the American South were often reflective of European roots and aspirations of grandeur; two upriver Mississippi River plantations, Nottoway near White Castle, Louisiana, and Sans Souci near Osceola, Arkansas, are two examples of this tradition.
It is widely known for its role in the Great Mississippi Flood of 1927. Several tons of dynamite were used to destroy the levee in hopes of preventing damage to the city of New Orleans. However, this effort became less than fruitful when the levee system was breached in several other areas to the north, preventing the flood waters from threatening New Orleans. It did cause major destruction in St. Bernard and Plaquemines Parishes.
Residents are zoned to schools in the St. Bernard Parish Public Schools.
As of 2007 Chalmette High School serves the population.
