Tome Jail is a historic jail building in Tome, New Mexico. It is the only surviving part of the former Valencia County Courthouse, built when the county seat was moved from Belen to Tome in 1875. The courthouse was a two-story adobe building which gradually disappeared due to erosion, but the jail had more durable stone walls and remained standing. Construction of the building was probably authorized by Probate Judge Manuel A. Otero, who was the chief county official at the time and whose name appears in a bilingual inscription carved into the stone lintel.
