Interstate 70 (I-70) is a mainline route of the Interstate Highway System in the United States connecting Cove Fort, Utah, to Baltimore, Maryland. In the US state of Kansas, I-70 extends just over 424 miles (682 km) from the Colorado border near the town of Kanorado to the Missouri border in Kansas City. I-70 in Kansas contains the first segment in the country to start being paved and to be completed in the Interstate Highway System. The route passes through several of the state's principal cities in the process, including Kansas City, Topeka, and Salina. The route also passes through the cities of Lawrence, Junction City, and Abilene.

The section of I-70 from Topeka to the Missouri border is co-designated as the Kansas Turnpike; only the section between Topeka and just west of Kansas City is tolled.
