Interstate 675 (I-675) is an auxiliary Interstate Highway in the suburbs of Dayton in the US state of Ohio. I-675 serves as an eastern bypass of Dayton that is 26.53 miles (42.70 km) long. As originally proposed, the route was to reconnect with I-75 north of Dayton near Northridge rather than going east toward Springfield and I-70. Construction was completed in 1987, though some have lobbied to extend the highway west of Dayton.

After the Prince George's County segments of MD 408 were removed in the late 1970s, the remaining state-maintained highway through Upper Marlboro became MD 725.
