It is the only Delhi Township statewide. The area of modern-day Delhi Township was first settled by European Americans in 1789 with the founding of the village of South Bend. A year later, when Hamilton County was incorporated, the village loaned its name to South Bend township, which included the present-day location of Delhi Township. In 1809, South Bend Township was divided into Green and Miami townships. Delhi was later split from the southern portions of Green Township in 1816 as a result of a petition from residents. Upon incorporation, the township's name was originally spelled as "Delhigh", although the name morphed into "Delhi" sometime in the nineteenth century for unknown reasons.
