K-20 is a 37.21-mile-long (59.88 km) west–east state highway in the northeastern part of the U.S. state of Kansas. It connects U.S. Route 75 (US-75) in the Kickapoo Nation Indian Reservation with K-7 southwest of Troy. Along the way, K-20 intersects several major highways, including U.S. Route 159 in Horton, and overlaps U.S. Route 73 from Horton to south of Everest. Northeast of Denton, the highway intersects K-120, which travels north to Severance and Highland. K-20 travels through mostly rural farmlands and is a two-lane highway its entire length.

Before state highways were numbered in Kansas, there were auto trails. K-20 overlaps the former Capitol Route near Horton. From Horton to south of Everest, the highway overlaps the former George Washington National Highway and King of Trails. The section from K-120 to Bendena overlaps the former Pikes Peak Ocean to Ocean Highway. K-20 was established by 1928, and at that time ran from US-73E south of Everest east to K-16 south of Troy. On July 11, 1956, it was approved to extend K-20 from US-73 west to US-75 as soon as the county had improved the roadway. Then by August 1956, the county had finished the required projects and it was officially extended.
