The Honorary Medal for Merits toward Museum Collections, also known as the Museum Medal, is one of the oldest civil decorations of the Netherlands. It was created by royal decree on 26 June 1817 by King William I of the Netherlands. The decree describes the following: "Erepenning voor blijken van belangstelling in 's Rijksverzamelingen door schenking betoond". The medal is awarded in gold, silver or bronze as a token of appreciation to those who "aan hen, die enig boek- of kunstwerk, dat de vrucht van hun arbeid was, de Koning deden toekomen".
