Route 163 is a short 0.30-mile-long (0.48 km) state highway in the county of Warren in New Jersey.

A still-existing bridge carries an abandoned ex-Delaware, Lackawanna and Western Railroad line across the river just north of the former road crossing.

The unsigned Route 163 runs from US 46 north to a dead end on the east side of US 46, all in Knowlton Township, New Jersey.

Route 163 passes several residences to the north and a short stretch of homes to the south.

Route 163 officially terminates at a barricaded dead-end near Hemlock Hill Lane.
