TheRumsen language (also known asRumsien,Rumsun,[2]San Carlos Costanoan andCarmeleno) is one of eightOhlone languages, historically spoken by theRumsen people ofNorthern California. The Rumsen language was spoken from thePajaro River toPoint Sur, and on the lower courses of the Pajaro, as well as on theSalinas andCarmel Rivers, and the region of the present-day cities ofSalinas,Monterey andCarmel.

One of eight languages within theOhlone branch of theUtian family, it became one of two important native languages spoken at theMission San Carlos Borroméo de Carmelo founded in 1770, the other being theEsselen language.
The last fluent speaker of Rumsen wasIsabel Meadows,[1] who died in 1939. TheBureau of American Ethnology linguistJohn Peabody Harrington conducted very extensive fieldwork with Meadows in the last several years of her life. These notes, still mostly unpublished, now constitute the foundation for current linguistic research and revitalization efforts on the Rumsen language.[1] The Costanoan Rumsen Carmel Tribe has been in the process of reestablishing their language. They have begun efforts to teach their tribal members Rumsen and are working to complete a revised English - Rumsen Dictionary.[citation needed]
Dialects of the Rumsen language were spoken by four independent local tribes, including theRumsen themselves, theEnsen of the Salinas vicinity, theCalendaruc of the central shoreline of Monterey Bay, and theSargentaruc of theBig Sur Coast. The territory of the language group was bordered by Monterey Bay and thePacific Ocean to the west, theAwaswas Ohlone to the north, theMutsun Ohlone to the east, theChalon Ohlone on the south east, and theEsselen to the south.[3]
