The Attack-class patrol boats were small coastal defence vessels built for the Royal Australian Navy (RAN) and operated between 1967 and at least 1991. Following their Australian service, twelve ships were transferred to Papua New Guinea and Indonesia.

A patrol boat is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine, estuarine, or river environments.
