Pirton is a large village and civil parish three miles northwest of Hitchin in Hertfordshire, England.

[2] The village was then known as Peritone (meaning 'Homestead of Pears')[3] The parish church, rebuilt in 1877, but with the remains of its 12th-century tower, is built within the bailey of a former castle, Toot Hill.

Pirton Grange, which was remodelled in the 18th century, is in the north of the parish, and is a particularly interesting, moated Elizabethan house with a timber-framed gatehouse.

The Icknield Way Path passes through the village on its 110-mile (180 km) journey from Ivinghoe Beacon in Buckinghamshire to Knettishall Heath in Suffolk.

The Icknield Way Trail, a multi-user route for walkers, horse riders and off-road cyclists also passes through the village.
