Wilhelm Heinrich Riehl (6 May 1823 – 16 November 1897) was a German journalist, novelist and folklorist.
Riehl was born in Biebrich in the Duchy of Nassau and died in Munich. Riehl was born into a settled middle-class background, was a professor at the University of Munich, and later in life a curator of Bavarian antiquities.
According to George Mosse,
Riehl argued that the 'working class' were the most respectable Volk, since they were best attuned to nature itself. Throughout his work, Riehl displays a strong conviction that the German people and land are intrinsically connected to one another. He also is considered the founder of the "German ethnographic Volkskunde" and drew many of his conclusions in his work from his personal experiences hiking throughout Germany.
