The Garden District is a neighborhood of the city of New Orleans, Louisiana, United States. A subdistrict of the Central City/Garden District Area, its boundaries as defined by the New Orleans City Planning Commission are: St. Charles Avenue to the north, 1st Street to the east, Magazine Street to the south, and Toledano Street to the west. The National Historic Landmark district extends a little farther.

St. Charles Avenue is a thoroughfare in New Orleans, Louisiana, U.S. and the route of the St. Charles Streetcar Line. It is also famous for the dozens of mansions that adorn the tree-lined boulevard for much of the uptown section of the boulevard. It is named for St. Charles Borromeo, patron saint of Charles III of Spain, the monarch when France transferred the then-vast territory of Louisiana to Spain at the conclusion of the Seven Years' War in 1763.
