Wilhelmsdorf () is a municipality in the district of Neustadt (Aisch)-Bad Windsheim in Bavaria in Germany.
Wilhelmsdorf was established by Huguenots. The village was named after the sovereign ruler George William, Margrave of Brandenburg-Bayreuth, who sheltered them. The Huguenot tradition is still a part of the village history. Sermons in the local Lutheran church were held in French until around 1900.
In the 19th century, Wilhelmsdorf was well known for their stocking-weavers. In 1903 the first compass factory was established. In the 20th century several competing compass factories were located at Wilhelmsdorf. Now Wilhelmsdorf has a compass museum.
Wilhelmsdorf should not be mistaken for Wilhermsdorf, a village 15 km away.
