K-63 is an approximately 58.8-mile-long (94.6 km) state highway in the U.S. state of Kansas. It is a north–south highway that serves small towns in the northeast part of the state. K-63's southern terminus is at U.S. Route 24 (US-24) in St. Marys and the northern terminus is a continuation as Nebraska Highway 50 (N-50) at the Nebraska border. The highway passes mostly through rural farmlands, however it does pass through the cities of Emmett, Havensville and Corning. It also passes along the edge of Seneca, where it has a short overlap with US-36.

Before state highways were numbered in Kansas there were auto trails. The southern terminus was part of the former Roosevelt National Highway and Golden Belt. The former Corn Belt Highway crosses K-63 in Havensville. A small section just south of Seneca and a few sections between Seneca and the Nebraska border follow the former Omaha-Topeka Trail. The highway also crosses the former Pikes Peak Ocean to Ocean Highway by Seneca. K-63 was first designated as a state highway in 1927. The highway has remained unchanged since, except for minor realignments by Emmett and Seneca.
