Mount Sunflower, although not a true mountain, is the highest natural point in the U.S. state of Kansas.[1] At 4,039 feet (1,231 m), it is 3,300 feet (1,010 m) above the state's topographic low point, which lies on the opposite side of the state.[3] It is located between the communities of Kanorado and Weskan in Wallace County, less than half a mile (0.8 km) from the state border with Colorado and is near the lowest point in Colorado.

Mount Sunflower is located on private land owned by Ed and Cindy Harold, who encourage visitors to the site.[4] Amenities include a picnic table, a little free library, a sunflower sculpture made from railroad spikes, and a plaque on the site stating, "On this site in 1897, nothing happened." Additionally, there is a mailbox on the site with a registration book inside where visitors can write their names, where they are from, and how many members are in their party.
