K-52 is an approximately 23-mile-long (37 km) east–west state highway in eastern Kansas. Its western terminus is at an intersection with K-31 southeast of Mound City. K-52 then overlaps U.S. Route 69 for eight miles (13 km) through Pleasanton and Trading Post, then splits off to the east. three miles (4.8 km) later, it crosses into Missouri, becoming Route 52.

Before state highways were numbered in Kansas there were auto trails. K-192 follows a short section of the former Jefferson Highway in Mound City. The former routing through Pleasanton follows the former Ozark Trails and Kansas City-Fort Scott-Miami-Tulsa Short Line. K-52 was first established as a state highway on January 7, 1937, and went from K-38 in Blue Mound northeastward to K-7 in Mound City. It was extended west then south to US-54 in Moran by the end of 1937. It was realigned to the west of Pleasanton in 1987 and eight years later, the highway was truncated to its current western terminus.
