New River is a 24.0-mile-long (38.6 km)[1] waterway located in south Louisiana in Ascension Parish.

Lack of river current has caused sediment to reduce both its depth and width.

New River originally meandered from Geismar passing through the city of Gonzales and the communities of St. Amant and Acy on its way to its mouth at Blind River.

During the early part of the twentieth century a 5-mile (8 km) canal, called the New River Canal, was constructed to Petite Amite River, to increase its velocity and distance to Lake Maurepas.
