The Grace Hudson Museum and Sun House in Ukiah, California, is an art, history and anthropology museum focusing on the lifeworks of artist Grace Carpenter Hudson (1865-1937) and her ethnologist husband, Dr. John W. Hudson (1857-1936). Changing interdisciplinary exhibitions and public programs feature Western American art, California Indian cultures, histories of California's diverse North Coast region, and the work of contemporary regional artists.

Since its inauguration in 1986, the Grace Hudson Museum and Sun House has become an increasingly important cultural and educational resource for Northern California. The Museum's collections consist of more than 30,000 interrelated objects, with significant holdings of Pomo Indian artifacts (particularly basketry) ethnographic field notes, unpublished manuscripts, historic photographs and the world's largest collection of Grace Hudson paintings. The Museum's exhibitions and public programs are thematically shaped by, and linked to, its collections with their focus on Western art, history and anthropology. The Museum also houses a gift store with jewelry, children's items, local artists' work, books, and t-shirts. The Museum sits on the four acre Hudson-Carpenter Park.
