Otwell was originally called Pierceville, being named after President Franklin Pierce, and under this name was laid out in 1855. The name was changed to Otwell in 1864 by a popular petition of its residents. The name had to be changed when the post office came because there was already a Pierceville in Indiana. The name Otwell is derived from the middle name of Robert Otwell Brown, the son of an early settler.
