Pinhook is an inactive village in Mississippi County, Missouri, United States. The population was 6 at the 2020 census, down from 30 in 2010.

It was settled in the 1920s or 1930s by sharecroppers. The community takes its name from a nearby ridge of the same name which in turn was so named on account it having the form of a pinhook. This largely African American community expanded to nearly 250 people at its peak.

The community was flooded in May 2011 when the U.S. Army Corps of Engineers breached the Bird's Point Levee to save the town of Cairo, Illinois. The government did not assist or provide help to evacuate Pinhook. The residents were left entirely on their own before the levee breach. Afterwards, the former residents resettled in East Prairie and Sikeston. In August 2015 the remaining buildings in Pinhook were bulldozed.
