Wilesco is the trade name of German toy company Wilhelm Schröder GmbH & Co. KG, known for manufacturing live steam toys such as steamrollers, traction engines, stationary steam engines, and numerous accessories such as countershafts and drive models.

This decision also helped the company weather the economic crisis of the late 1920s and early 1930s because these toys were also exported to the US.

Wilesco's main rival is the British-based steam model manufacturer: Mamod.
