K-103 (Kansas highway)

K-103 is a 6.980-mile-long (11.233 km) east–west state highway located entirely in Cherokee County in the U.S. state of Kansas. K-103's western terminus is at K-7 south of the City of Cherokee and the eastern terminus is at U.S. Route 69 (US-69), US-160 and US-400 south of the City of Pittsburg. Along the way the route passes through the City of Weir.

K-103 was designated as a state highway by 1936, and extended from US-160 east to US-69. Then in 1958, US-160 was realigned east along K-103 from K-103's original western terminus to K-7 then continued east along K-104 to US-69, and at that time K-103 was truncated to its current western terminus.
