Gustavus Vaughan Brooke (25 April 1818 – 11 January 1866) was an Irish stage actor who enjoyed success in Ireland, England and Australia.
Brooke was born in Dublin, Ireland, the eldest son of Gustavus Brooke (died 1827), a graduate of Trinity College, Dublin, and his wife Frances, daughter of Matthew Bathurst. He was educated at a school at Edgeworthstown under Lovell Edgeworth, a brother of the novelist Maria Edgeworth, and afterwards at Dublin at a school run by the Rev. William Jones. There he showed talent in a school play; when he was allowed to see William Charles Macready perform in Dublin in March 1832 he was determined to go on the stage. He interviewed Calcraft, the manager of the Dublin Theatre, and early in 1833 on account of the failure of Edmund Kean to fulfil his engagement at Dublin, Brooke was given an opportunity to appear in the part of William Tell. He was billed as "a young gentleman under 14 years of age" (he was really almost 15) and played with some success. Other appearances followed as Virginius and Young Norval. He appeared at the Royal Victoria Theatre, London, in October 1834 as Virginius with little success.
Brooke toured the English provincial theatres for three years, and then played a season at Dublin in October 1837. He had a qualified success, which was followed by a more successful season at Belfast in January 1838. He continued to play in the provinces and in Ireland, and in 1841 accepted an engagement with Macready's company in London, but finding himself cast for a small part declined the role. He returned to the provinces and refused several offers of parts in London. He had successful seasons at Manchester, Liverpool and other large towns, among his characters being Richard III, Romeo, Macbeth, Virginius, Hamlet, Othello, Iago and Brutus. He played Othello to Macready's Iago at Manchester. Later on he was with Edwin Forrest, and in October 1846 took the part of Romeo at Dublin to Helena Faucit's Juliet. Other roles opposite Faucit included Claude Melnotte, Orlando, Hamlet, Macbeth, Richard III, Sir Giles Overreach, Leontes and Faulconbridge.
