Carrollton is a neighborhood of uptown New Orleans, Louisiana, USA, which includes the Carrollton Historic District. It is the part of Uptown New Orleans farthest up river from the French Quarter. It was formerly a separate town incorporated in 1833, and was annexed by New Orleans in 1874 (becoming the 16th Ward and 17th Ward of the city) but has long retained some elements of distinct identity.
Historically the boundaries of the city of Carrollton were the Mississippi River, the downriver border of Jefferson Parish, Louisiana, Fig Street, and Lowerline Street. As Lowerline is a small street, some people think of the neighborhood of Carrollton as extending two blocks further to the larger thoroughfare of Broadway. The area on the river side of Claiborne Avenue is sometimes referred to as "Old Carrollton". The incorporation of Carrollton creates an apparent anomaly in New Orleans street names; Lowerline is upriver from Upperline Street, which was originally the upriver boundary of another suburb annexed in the 1850s.
