The Soviet Project 183R class, more commonly known as the Komar class, its NATO reporting name, meaning "mosquito", is a class of missile boats, the first of its kind, built in the 1950s and 1960s. Notably, they were the first to sink another ship with anti-ship missiles in 1967.

A missile boat or missile cutter is a small, fast warship armed with anti-ship missiles. Being smaller than other warships such as destroyers and frigates, missile boats are popular with nations interested in forming a navy at lower cost. They are similar in concept to the torpedo boats of World War II; in fact, the first missile boats were modified torpedo boats with the torpedo tubes replaced by missile tubes.
