Neptune takes 16 hours, 6 minutes and 36 seconds to rotate once on its axis. That's about 2/3rds of an Earth Day.
Note that the period of rotation is measured by watching Neptune's magnetic field. The time cited is the time it takes the "whole planet" to rotate once on its axis. This is important because Neptune is not solid - it's a big gas planet, and the atmosphere is rotating at different speeds.
It is very difficult to determine how fast one of the gas giant planets is rotating. A recent study by the University of Arizona revealed that Neptune spins one entire rotation every 15 hours, 57 minutes, and 59 seconds.
Before this study, Neptune's rotation time had been assumed to be around 16 hours, 6 minutes.
Neptune rotates in very slightly over 16 hours.
