Thisted Museum opened on June 7, 1905, initiated by vice headmaster P. L. Hald, who remained the museum's director for more than half a century until his death in 1958. Initially located in the basement of the Technical School in Kr. Koldsgade, in 1917 it moved to the neighboring building in Skolegade. In 1939, it inherited the villa at Jernbanegade 4 from the town's wealthiest man, coffee merchant Spangberg, and has been housed there ever since, overlooking the old cemetery and Store Torv.
In recent decades, the museum has gradually professionalized and modernized. After the municipal reform in 1970, the name changed to the Museum of Thy and Vester Hanherred to signal that it covered the entire region's history and not just that of the old market town. The following year, the first academically trained leader took charge, and the staff has been continuously expanded since.
Over time, the museum has also acquired several departments and exhibition sites. In 1970, it took responsibility for author Johan Skjoldborg's childhood home in Øsløs, which had been a museum since 1961. From 1977-91, warehouses were located on Munkevej in Thisted before taking over the closed school in Vang, where the warehouses and the archaeological department are still located.
In 1991, the Heltborg Museum opened in Sydthy with its unique combination of art and cultural history. In 2000, the Vorupør Museum opened its doors in an old boatyard, and in 2005, it acquired a protected 18th-century fisherman's house in Agger.
In 2014, the museum changed its name to the more straightforward Museum Thy, and as the latest addition, the Bunkermuseum Hanstholm, the country's leading museum on the history of the occupation, became part of the family on January 1, 2018. Additionally, there are numerous smaller exhibitions around the region, making the museum physically present throughout the area.
