Carrollton is a neighborhood of uptown New Orleans, Louisiana and is the part of Uptown New Orleans furthest up river from the French Quarter. It was formerly a separate town incorporated in 1833, and 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, Claiborne Avenue, and Lowerline Street. The main street is broad Carrollton Avenue, lined with live oaks, with the St. Charles Avenue Streetcar running on the "neutral ground." The streetcar barn is a block off the avenue in Carrollton. The old Neoclassical Carrollton city hall building is on Carrollton Avenue near the Mississippi; today it houses Lusher Extension Middle School.

As Carrollton Avenue extends further inland beyond Claiborne, some people (especially from other parts of New Orleans) sometimes think of that area as part of Carrollton as well; sometimes the phrase "Old Carrollton" is used to refer to the stricter boundaries.

The neighborhood and Avenue are pronounced "Care-ol-ton" by residents and other uptowners, but many people from the downtown parts of New Orleans pronounce the names as "Karl- ton".

In addition to Carrollton Avenue and Saint Charles Avenue, the neighborhood still retains two "neighborhood main streets" of mixed residential and commercial use. Lower Carrollton centers on Maple Street, with many restaurants, coffee houses, bars, and upscale shops. Upper Carrollton has Oak Street, formerly hosting somewhat larger businesses (such as Woolworth); current businesses there range from restaurants and a hardware store to the best known of the neighborhoods live music venues, the Maple Leaf Bar. Tulane University and Loyola University are just a few blocks below Carrollton. On Carrollton at Claiborne Avenue is Palmer Park, which hosts some moderate sized live music festivals each year and has a monument to the Carrolltonians who died in World War I.

As of 2004, the United States Postal Service still delivers mail addressed either as "Carrollton, Louisiana" or "New Orleans, Louisiana. The ZIP Code is 70118. During New Orleans Mardi Gras celebrations, the Krewe of OAK parades through Carrollton.
