Poydras is a census-designated place (CDP) in St. Bernard Parish, Louisiana, United States. The population was 3,886 at the 2000 census. It is part of the New Orleans–Metairie–Kenner Metropolitan Statistical Area. Poydras is on the East Bank of the Mississippi River, just upriver from the Plaquemines Parish line.
Poydras was first settled in the 18th century by Isleños when Louisiana was a Spanish colony. Presumably, the town is named for Julien Poydras.
Albert Estopinal, Jr., a St. Bernard Parish district attorney, judge, and sheriff, was born in Poydras in 1869 to later U.S. Representative, Albert Estopinal, Sr.
The locally constructed levee failed during the 1922 flood and the community of Poydras was destroyed. Some historians claim that the levee break was intentional to save the City of New Orleans.
