The Royal Mile is a succession of streets forming the main thoroughfare of the Old Town of the city of Edinburgh in Scotland. The term was first used descriptively in W. M. Gilbert's Edinburgh in the Nineteenth Century (1901), describing the city "with its Castle and Palace and the royal mile between", and was further popularised as the title of a guidebook by R. T. Skinner published in 1920, "The Royal Mile (Edinburgh) Castle to Holyrood(house)".

The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of distance; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. The statute mile was standardised between the Commonwealth of Nations and the United States by an international agreement in 1959, when it was formally redefined with respect to SI units as exactly 1,609.344 metres.
