OCCAR (Organisation Conjointe de Coopération en matière d'ARmement) is a European organisation for coordinating the procurement of purchases of weapon systems by European countries.
OCCAR was established on the 12 November 1996 by the Defence Ministers of France, Germany, Italy and the UK.
Other European nations may join OCCAR, subject to their actual involvement in a substantive collaborative equipment programme involving at least one OCCAR partner and acceptance of OCCAR's founding principles, rules regulations and procedures. In May 2003, Belgium became the fifth OCCAR member state. Spain joined the organisation in January 2005 in relation to the A400M and Tiger helicopter programme.
