The Chalon language is one of eight Ohlone languages, historically spoken by the Chalon people of Native Americans who lived in Northern California. Also called Soledad, it belongs to one of the Ohlone (or Costanoan) languages of the Utian family. It is poorly attested, the only documentation originating from wordlists in the 19th century and a fragment of a catechism. Recent work suggests that Chalon may be transitional between the northern and southern groups of Ohlone languages.
