Andrew Beaton (died 1577) was a Scottish courtier, and Master of the Household to Mary, Queen of Scots in England.
One of his brothers, James Beaton, was Archbishop of Glasgow, who became an important ally of Mary, Queen of Scots, after she was deposed in Scotland.
In 1565 Andrew Beaton carried letters from Charles IX of France and Catherine de' Medici to Mary, Queen of Scots and Lord Darnley.
On Beaton's return, Mary attempted to bolster confidence in her rule by claiming Elizabeth would not meddle in the quarrel between her and her lords.
Mary wrote to him from Sheffield Castle on 22 August 1577, with political news, instructions, and a reminder to get her some novelties from the shops in Paris.
