The Royal Canal (Irish: An Chanáil Ríoga) is a canal originally built for freight and passenger transportation from the River Liffey in Dublin to Longford in Ireland. The canal fell into disrepair in the late 20th century, but much of the canal has since been restored for navigation. The length of the canal to the River Shannon was reopened on 1 October 2010, but the final spur branch of the canal to Longford Town remains closed.

In 1755, Thomas Williams and John Cooley made a survey to find a suitable route for a man-made waterway across north Leinster from Dublin to the Shannon. They originally planned to use a series of rivers and lakes, including the Boyne, Blackwater, Deel, Yellow, Camlin and Inny and Lough Derravaragh. A disgruntled director of the Grand Canal Company sought support to build a canal from Dublin to Tarmonbarry, on the Shannon in North county Longford.

Work commenced in 1790 and lasted 27 years before finally reaching the Shannon in 1817, at a total cost of £1,421,954. Building was unexpectedly expensive and the project was riven with problems; in 1794 the Royal Canal Company was declared bankrupt. The Duke of Leinster, a board member, insisted that the new waterway take in his local town of Maynooth. The builders had to deviate from the planned route and necessitated the construction of a 'deep sinking' between Blanchardstown and Clonsilla. The diversion also called for the building of the Ryewater Aqueduct, at Leixlip.

The original 1796 fare from Dublin to Kilcock was 1/1, much cheaper than the stagecoach.

The canal passes through Maynooth, Kilcock, Enfield, Mullingar and Ballymahon has a spur to Longford. The total length of the main navigation is 145 kilometres (90 mi), and the system has 46 locks. There is one main feeder (from Lough Owel), which enters the canal at Mullingar.

In 200 years it has been maintained by eight successive agencies: the Royal Canal Company, the Commissioners of Inland Navigation, the New Royal Canal Company, Midland Great Western Railway Company, Great Southern Railways, CIÉ, and (from 1986) the Office of Public Works.
