Streetcars in New Orleans have been an integral part of the city's public transportation network since the first half of the 19th century. The longest of New Orleans' streetcar lines, the St. Charles Avenue line, is the oldest continuously operating street railway system in the world. Today, the streetcars are operated by the New Orleans Regional Transit Authority (RTA).

Light rail transit (LRT) is a form of passenger urban rail transit characterized by a combination of tram and rapid transit features. While its rolling stock is similar to that of a traditional tram, it operates at a higher capacity and speed and often on an exclusive right-of-way. In many cities, light rail transit systems more closely resemble, and are therefore indistinguishable from, traditional underground or at-grade subways and heavy-rail metros.
