Piddlehinton is a village and civil parish in west Dorset, England, situated in the Piddle valley north of Dorchester. In the 2011 census the parish had a population of 403. Piddlehinton formerly constituted a liberty containing only the parish itself.
The local schools are Piddle Valley First School, St Mary's Middle School in Puddletown, and The Thomas Hardye School in Dorchester, members of the DASP group. The village has one public house called The Thimble, but no shop or post office. In the adjacent settlement of White Lackington is another public house, called The European, though this is within the neighbouring civil parish of Piddletrenthide. The nearest shop is also in Piddletrenthide. St Mary's Piddlehinton is the local church. A microbrewery—the Dorset Piddle Brewery—was established in Piddlehinton in 2008 and produces 300 gallons of ale every week.
During the build-up to D-day the US Army operated from an airstrip in Piddlehinton using Piper L-4 Grasshoppers of the 62nd Armed Field Artillery Battalion. The L-4 Grasshopper was a light aircraft that was widely used by the US Air Force for observation and liaison during the Second World War. It was called the Grasshopper because of its ability to take of and land on any sort of terrain and in very limited space. The exact location of the airstrip in Piddlehinton is unknown.
