Bishop's Waltham is a town in Hampshire, England with a population of around 6,500 people. In 904, it was given by the king to the Bishop of Winchester. In 1136 Henry du Blois, a later bishop built the now-ruined Bishops Waltham Palace.

William of Wykeham died in the town, while after the Battle of Trafalgar, some French sailors including Admiral Villeneuve were imprisoned there.

There are many Georgian buildings in the town alongside the Norman parish church. Unusually for Britain, there is a vineyard nearby.
