39°07′47″N 96°26′26″W / 39.129720°N 96.440555°W / 39.129720; -96.440555 Pillsbury Crossing is a natural limestone slab that was used by pioneers to cross Deep Creek. The ledge terminates in a waterfall in Riley County, Kansas, USA. The waterfall is about 40 feet (12 m) wide and has a drop of around 5 feet (1.5 m). Below Pillsbury Crossing, Deep Creek flows into the Kansas River.

The waterfall is named for Josiah Pillsbury, a Free-State settler in Kansas Territory who homesteaded near the crossing in 1855. Pillsbury was a member of the Free-State Topeka Legislature and the failed Leavenworth Constitutional Convention.

The site is part of Pillsbury Crossing Wildlife Area.
