The Staplehurst rail crash was a derailment at Staplehurst, Kent, on 9 June 1865 at 3:13 pm. The South Eastern Railway Folkestone to London boat train derailed while crossing a viaduct where a length of track had been removed during engineering works, killing ten passengers and injuring forty. In the Board of Trade report it was found that a man had been placed with a red flag 554 yards (507 m) away but the regulations required him to be 1,000 yards (910 m) away and the train had insufficient time to stop.

Staplehurst is a village and civil parish in the borough of Maidstone in Kent, England, 9 miles (14 km) south of the town of Maidstone and with a population of 6,003. The village lies on the route of a Roman road, which is now incorporated into the course of the A229. The name Staplehurst comes from the Old English 'stapol' meaning a 'post, pillar' and 'hyrst', as a 'wooded hill'; therefore, 'wooded-hill at a post', a possible reference to a boundary marker at the position of All Saints' church atop the hill along the road from Maidstone to Cranbrook. The parish includes the hamlet of Hawkenbury.
