Hammerton's Ferry is a pedestrian and cycle ferry service across the River Thames in the London Borough of Richmond upon Thames, London, England. The ferry links the northern bank near Marble Hill House in Twickenham with the southern bank near Ham House in Ham. It is one of only four remaining ferry routes in London not to be replaced by a bridge or tunnel.

In 1908, local resident Walter Hammerton began hiring out boats to leisure users from a boathouse opposite Marble Hill House, and in 1909 began to operate a regular ferry service across the river at this point using a 12-passenger clinker-built skiff, charging 1d per journey. In 1913, William Champion, and Lord Dysart, operators of the nearby Twickenham Ferry, took legal action against Hammerton to remove his right to operate the ferry. Although Hammerton won the initial case, the judgement was reversed on appeal. Following considerable public interest in the case, a public subscription raised the funds for Hammerton to take the case to the House of Lords, which ruled in his favour on 23 July 1915.
