U.S. Route 11 (US 11) is a north–south United States highway extending 1,645 miles (2,647 km) across the eastern United States. The southern terminus of the route is at U.S. Route 90 in the Bayou Sauvage National Wildlife Refuge in eastern New Orleans, Louisiana. The northern terminus is at the Rouses Point - Lacolle 223 Border Crossing in Rouses Point, New York. The route continues across the border into Canada as Quebec Route 223. US 11, created in 1926, largely follows the route of the original plan.

Until 1929, US 11 ended just south of Picayune, Mississippi at the Pearl River border with Louisiana. It was extended through Louisiana after that.

The Maestri Bridge, which carries US 11 across Lake Ponchartrain, served as the only route to New Orleans from the east for six weeks after Hurricane Katrina due to its sturdy construction. The storm virtually destroyed the Twin Span Bridge on I-10 and damaged the Fort Pike Bridge on US 90.
