The FV603 Saracen is a six-wheeled armoured personnel carrier designed and produced by Alvis from 1952 to 1976. It has been used by a variety of operators around the world and is still in use in secondary roles in some countries. The Saracen became a recognisable vehicle as a result of its part in Operation Banner in Northern Ireland as well as for its role in the South African government's enforcement of apartheid.

Alvis Car and Engineering Company Ltd was a British manufacturing company in Coventry from 1919 to 1967. In addition to automobiles designed for the civilian market, the company also produced racing cars, aircraft engines, armoured cars and other armoured fighting vehicles.
