The Chichicastenango Regional Museum or Museo Regional is a museum in Chichicastenango, Guatemala. It is located at the Iglesia de Santo Tomás and has a number of noted ancient artifacts in jade, stone, and ceramic. Some of the clay figurines and ancient clay pots date back to 1200. It also contains a number of obsidian spear and arrow heads found in the area.
The museum is often called Museo Arqueológico Rossbach because a significant part of the collection was donated by Idelfonso Rossbach, a German Franciscan priest who served in the town from 1894-1944.
