The Mill Creek is a stream in southwest Ohio. It flows 28.4 miles (45.7 km)^[1] southwest and south from its headwaters in Liberty Township of Butler County through central Hamilton County and the heart of Cincinnati into the Ohio River just west of downtown. The section of Interstate 75 through Cincinnati is known as the Mill Creek Expressway.

The Mill Creek Valley is a remnant of the Deep Stage Ohio River from the days of the Last Glacial Maximum. The stream, with its water power and valley, were important to the development of Cincinnati. Then, for a time, the steep hillsides that surround the creek limited expansion and gave impetus to the free growth of surrounding communities that were over that barrier. Finally, inclined planes solved the problem, before highways and automobiles eliminated it.
