Baron of Renfrew is a dignity in the Baronage of Scotland held by the heir apparent to the British throne, currently Prince William, Duke of Rothesay.

An act of the Scottish Parliament passed in 1469 confirmed the pattern of succession.

[2] Renfrew, a town near Glasgow, is sometimes called the "cradle of the royal Stewarts".

Some, however, claim that the Act of 1469 effectively elevated the Barony of Renfrew to the dignity of a peerage.

The title of Lord Renfrew was used by the traveling Prince of Wales, later King Edward VII,[5] and by Prince Edward, Duke of Rothesay, later King Edward VIII and then Duke of Windsor, when he traveled in a private capacity or when he wished to pay visits 'incognito'.
