The Czechoslovak War Cross 1918 (Československý válečný kříž 1918 in Czech, Československý vojnový kríž 1918 in Slovak) is a military decoration of the former state of Czechoslovakia which was issued for acts of military valour during the years of the First World War.

The medal was first created on November 7, 1918, and issued to Czechoslovak citizens and also, upon application, to citizens of Germany and Austria who had served in the Czechoslovak armed forces ( e.g. Czechoslovak Legions) during the years of the Great War with distinction and bravery, and also during border conflicts with Poland and Hungary.

The Czechoslovak War Cross was also, on occasion, issued to veterans of the Allied powers who had played a large role in World War I and were considered contributors to the formation of the Czechoslovak state.

John J. Pershing was one such recipient of the Czechoslovak War Cross.

On the reverse the circles featured vermeil linden leaves, with the letters "ČS" (Československo, meaning Czechoslovakia)[1][2] in the middle.
