Interstate 510 (I-510) is a short spur route of I-10 within eastern New Orleans, Louisiana, United States. It runs south from I-10, intersects with U.S. Route 90, and ends at the Almonaster Boulevard interchange, near the NASA Michoud Assembly Facility. From this point, the highway continues south over the Gulf Intracoastal Waterway / Mississippi River Gulf Outlet on the Green Bridge.

The Interstate spur route is a portion of Paris Road, a New Orleans metropolitan area roadway stretching from the Mississippi River to Lake Pontchartrain dating back to the 19th century. The portion designated I-510 is entirely within the Ninth Ward of New Orleans, though the area the highway runs through is locally known as New Orleans East.
