The North Coast Overnight Express was an Australian passenger train operated by the State Rail Authority from July 1982 until November 1988.

It operated from Sydney via the North Coast line to Murwillumbah.

It was formed of air-conditioned HUB/RUB stock but despite being a night train, conveyed no sleeping accommodation.

Its headcode was NL5/NL6.

In October 1985, it was truncated to Grafton[1] and ceased operating in November 1988.
