Duke of Rothesay (, ) is a title of the
heir apparent to the British throne, currently
Prince Charles. It was a title of the heir apparent to the throne of the
Kingdom of Scotland before
1707, of the
Kingdom of Great Britain from 1707 to
1801, and now of the
United Kingdom of Great Britain and Northern Ireland. It is the title mandated for use by the heir apparent when in
Scotland, in preference to the titles
Duke of Cornwall (which also belongs to the eldest living son of the monarch, when and only when he is also heir apparent, by right) and
Prince of Wales (traditionally granted to the heir apparent), which are used in the rest of the United Kingdom and overseas. The Duke of Rothesay also holds other Scottish titles, including those of
Earl of Carrick,
Baron of Renfrew,
Lord of the Isles and
Prince and Great Steward of Scotland. The title is named after
Rothesay on the
Isle of Bute,
Argyll and Bute, but is not associated with any legal entity or landed property, unlike the
Duchy of Cornwall.
