Grünenberg was a medieval Swiss noble family. The family was active from the middle of the 12th century until the 15th century in the Swiss Plateau, mostly in the Bernese Oberaargau. There were two major branches, the Grimme and Schnabel lines which then further divided into other branches. Some of these branches owned land in Alsace and in southern Bavaria, especially in the Markgräflerland and in Breisgau. About one hundred members of the family are known today. The family name comes from Grünenberg Castle in Melchnau in the Canton of Bern.
