The Riverfront Streetcar Line is a historic streetcar line in New Orleans, Louisiana. It is operated by the New Orleans Regional Transit Authority (RTA). It was built along the east bank of the Mississippi River, in an area with many amenities catering to tourists. It opened August 14, 1988, making it the first new streetcar route in New Orleans in 62 years. The line runs 2 miles (3.2 km) from Julia Street at the upper end of the New Orleans Convention Center to the downriver (far) end of the French Quarter at the foot of Esplanade Avenue. Unlike the other three lines, it travels on an exclusive right-of-way, along the river levee beside New Orleans Belt Railway tracks, making it more akin to a light rail line. The line was regauged in 1997 from standard gauge to broad gauge. Officially, the Riverfront Line is designated Route 2 and is designated with a blue color on most RTA publications.

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).
