The Memoirs of Captain Rock is an 1824 satirical novel by the Irish writer Thomas Moore.

[1] It was released the same year as the destruction of his friend Lord Byron's Memoirs which had left Moore £2,000 poorer.

Moore had been long resident in England, and was a noted figure in Regency society in Whig circles, but retained an interest in Irish affairs and supported the Catholic Committee which sought to abolish the penal laws.

Moore had initially intended travel in the company of his friend Lord John Russell, the future Prime Minister, who had to pull out at the last moment.

On returning to his Wiltshire home near Bowood, he wrote the piece as a diversion from his work on his biography of Richard Brinsley Sheridan.
