Delhi Township is a township of Hamilton County, Ohio, located southwest of Cincinnati, Ohio. As of 2000, the total population is 30,104. The area is called Delhi Hills by most residents, due to the nature of the landscape. The rolling hills, and some steep hillsides are caused by its location. The township covers the slopes leading down to the Ohio River floodplain, and is cut by a number of ravines cause by streams that make the descent.

The area is largely a residential suburb of Cincinnati, but the College of Mount St. Joseph is located here.
