Chita District was one of the ancient districts of Owari Province and is mentioned in Nara period records. One of the castles that guarded the area was Ōno Castle.

Modern Chita District dates to the cadastral reforms of the early Meiji period, and was initially given to Nukata Prefecture in former Mikawa Province, whereas the holdings of former Owari Domain became Nagoya Prefecture. With the creation of Aichi Prefecture, Chita District again came to be considered part of former Owari Province.
