The Museum of Sologne is a museum dedicated to the history and culture of the Sologne region, located in Romorantin-Lanthenay, France, comprising the Chapter Mill, Town Mill and Jacquemart Tower.

Exhibits in the Chapter Mill tell the story of the manufacturing of textiles (sheets) and the economy of the city.

On the upper floor, there is also an exhibition dedicated to Leonardo da Vinci's projects.

In 2011, Carlo Pedretti, an Italian historian and honorary citizen of the town of Romorantin-Lanthenay, donated a facsimile of the Codex Arundel to the museum.
