The Croix de guerre (French) or Oorlogskruis (Dutch) is a military decoration of the Kingdom of Belgium established by royal decree on 25 October 1915.

The award was reestablished on 20 July 1940 by the Belgian government in exile for recognition of bravery and military virtue during World War II.

[3] The World War I Croix de guerre was established by royal decree on 25 October 1915 as an award for bravery or other military virtue on the battlefield.

It was also awarded to volunteers older than 40 or younger than 16 after a minimum of 18 months of service, to escaped prisoners of war rejoining the armed forces, and to military personnel who were placed on inactive duty because of injury.

It had a 14mm in diameter central medallion bearing the relief image of a "lion rampant" on its obverse and the royal cypher of King Albert I on its reverse.

[3] The post-1954 (or current) Croix de guerre is similar to the previous variants but with a different reverse center medallion now bearing the Coat of arms of Belgium in lieu of a royal monogram.
