Museum de Oude Wolden is a regional museum in the village of Bellingwolde in the Netherlands. The museum focuses on art and history of the regions of Oldambt and Westerwolde. It opened on 10 August 1973. In the first decades, it primarily exhibited historical objects documenting everyday life. In the late 1990s, the museum started to exhibit artworks of artist collective De Ploeg and magic realist painter Lodewijk Bruckman. Since 2012, it has a permanent display of paintings by Bruckman and temporary exhibitions.
The municipality of Bellingwedde employs the museum staff and provides most of the museum's budget. Since 2003, the museum had around 1,800 to 3,200 visitors per year. With 1,798 visitors in 2012, when the museum was partially closed for renovation, it is one of the lesser-visited museums in Groningen.
