The Group Medal of the Four Day Marches (Dutch: Groepsmedaille van der Vierdaagse) is a non wearable bronze presentation medal awarded to each registered group who successfully completes all four days of the International Four Days Marches Nijmegen (Vierdaagse in Dutch) held annually at Nijmegen, Netherlands.

The medal is awarded by the KNBLO, (Koninklijke Nederlandsche Bond Voor Lichamelijke Opvoeding, or Royal Dutch League for Physical Education) who organise the March.

As well as the Vierdaagse at Nijmegen, the medal was also awarded to groups who took part in the four day marches organised in various locations in the Dutch East Indies between 1935 and 1939.

Until 1977 the medal bore the image of the reigning Queen, first Wilhelmina then, from 1951 – once a new portrait has been approved – Juliana.

The medal is sometimes seen with the name of the military unit or walking club engraved within the wreath, along with the year of award.
