The Frietmuseum (Fries museum) is a museum in Bruges, Belgium, which is devoted to the history of potatoes and the production of Belgian fries. It describes itself as “the first and only museum dedicated to potato fries”.

The Frietmuseum is located in the Gothic Saaihalle (former wool hall) at Vlamingstraat 33. This is one of the oldest buildings in the World Heritage listed historic centre of Bruges and dates back to 1399, with an annexe added shortly afterwards.

The museum is spread across three floors. Exhibits on the ground floor trace the history of potatoes, beginning in Peru c.8000BC. The first floor details the history of fries, and their origins in Belgium. The basement of the building houses a cafe. Exhibits include photographs, artwork, historical potato peelers and chip-making machines, and a video outlining how to make perfect fries.
