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), "...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)".
