The Westbury or Bratton White Horse is a hill figure on the escarpment of Salisbury Plain, approximately east of Westbury in Wiltshire, England. Located on the edge of Bratton Downs and lying just below an Iron Age hill fort, it is the oldest of several white horses carved in Wiltshire. It was restored in 1778, an action which may have obliterated another horse that had occupied the same slope. A contemporary engraving from the 1760s appears to show a horse facing in the opposite direction that was rather smaller than the present figure. There is, however, no documentation or other evidence for the existence of a chalk horse at Westbury before 1742.
