Industrial Canal

The Industrial Canal is a 5.5 mile (9 km) waterway in New Orleans, Louisiana, United States. The waterway's proper name, as used by the U.S. Army Corps of Engineers and on NOAA nautical charts, is Inner Harbor Navigation Canal (IHNC). The more common "Industrial Canal" name is used locally, both by commercial mariners and by landside residents.

The canal connects the Mississippi River to Lake Pontchartrain. It separates New Orleans East from the rest of the city of New Orleans, and the Lower 9th Ward from the Upper 9th Ward. Approximately half of the waterway's course, from Industrial Lock to a point north of the Florida Avenue Bridge, is confluent with both the Gulf Intracoastal Waterway and the Mississippi River Gulf Outlet (MRGO).

The entirety of the canal passes through the 9th Ward of the city. Along the riverfront, the canal constitutes the boundary of the Upper 9th Ward's Bywater neighborhood on the upriver side of the canal and the Lower 9th Ward neighborhood on the downriver side. Near the lake, it is generally considered to be the eastern boundary of the Gentilly neighborhood and the western boundary of New Orleans East.
