Holwell is a small village and a civil parish two miles north of Hitchin in Hertfordshire, England, near the Bedfordshire border. At the 2011 Census the population of the village was 362. The church is unusual and, although largely rebuilt, retains some Perpendicular features and an interesting brass to Richard Wodehouse. The school, almshouses, and rectory are all in a similar Tudor style erected in the 1830s, but are no longer in use and have been converted into housing. Fragments of early wall paintings and wooden mullioned windows have been discovered in the mediaeval timber-framed Church Farmhouse.

It is not to be confused with Holwell Court, near Essendon, also in Hertfordshire.
