K-7 is a 240.606-mile-long (387.218 km) state highway in the U.S. state of Kansas. It is mostly a small country highway winding its way through the Osage Questas and Glaciated Regions of eastern Kansas, although a portion of the highway passes through the Kansas City metropolitan area. Significant portions of the highway overlap with U.S. Route 169 (US-169) and US-73. It also has junctions with two Interstate highways, Interstate 35 (I-35) in Olathe and I-70 in Bonner Springs. The portion of K-7 between Leavenworth and the Nebraska state line has been designated the "Glacial Hills Scenic Byway."
