Hills Bank and Trust Company is a bank based in Hills, Iowa, U.S.A., with 14 offices in three eastern Iowa counties, with more than 425 employees and total assets approaching $2 billion. While still headquartered in a town of fewer than 700 people, Hills Bank is one of the largest independent banks in Iowa, with over 117,000 customers. The bank was founded in 1904, and is a subsidiary of Hills Bancorporation, a holding company established on December 12, 1982. The bank's president is Dwight O. Seegmiller.

For many years, Iowa banking law allowed banks to establish a bank branch only in towns where the boundaries were contiguous. In 1979, the city of Hills annexed their small town to Iowa City by way of the old Rock Island Railroad track, which connected Hills to Iowa City.^[9] This annexation provided an opportunity for the first Hills Bank location to be opened outside of Hills, in the city of Iowa City. Hills Bank could then better serve its customers in the Iowa City area.
