Princes Street is one of the major thoroughfares in central EdinburghScotland, and the main shopping street in the capital. It is the southernmost street of Edinburgh's New Town, stretching around 1 mile (1.6 km) from Lothian Road in the west, to Leith Street in the east. The street has virtually no buildings on the south side, allowing panoramic views of the Old TownEdinburgh Castle, and the valley between.

Princes Street was originally to have been called St Giles Street after the patron saint of Edinburgh. However, King George III rejected the name, St Giles being also the patron saint of lepers and the name of a notorious 'rookery' of slums in London. The street is named after King George's two eldest sons, the Prince George, Duke of Rothesay (later King George IV) and the Prince Frederick, Duke of York and Albany.
