High Halstow is a village and civil parish on the Hoo Peninsula in the unitary authority of Medway in South East England. It was, until 1998, part of Kent and is still ceremonially associated via the Lieutenancies Act. The parish had a population of 1,781 according to the 2001 census.
Originally known as Hagelstowe, Hagelsto or Agelstow, it was named from an Old English word denoting a high, holy place. The area has been occupied by Romans, Saxons and Normans.
The village lies on the junction of the ancient roads from Hoo and Cliffe to the Isle of Grain, now a crossroads to the north of the A228 road. One of the highest points on the Hoo peninsula, at 30 to 50 metres above sea level, the modern village consolidates into a single community the four hamlets of Clinch Street, Fenn Street, Sharnal Street and High Halstow Street.
High Halstow was a civil parish in Hoo Rural District from 1894 until 1934, in Strood Rural District from 1934 until 1974, and since 1974 has been part of the Medway unitary authority. There is also a Lower Halstow (redirected here).
