Alan Ridout (9 December 1934 – 19 March 1996) was a British composer and teacher.
Born at West Wickham, Greater London, England, Alan Ridout studied briefly at the Guildhall School of Music before commencing four years of study at the Royal College of Music, London with Herbert Howells and Gordon Jacob. He was later taught by Michael Tippett, Peter Fricker and (under a Dutch government scholarship) Henk Badings.
He went on to teach at the Royal College of Music, the University of Birmingham, the University of Cambridge, the University of London, and at The King's School, Canterbury. He also broadcast musical talks on the radio.
His works include church, orchestral and chamber music, much of it for children. His style is mostly tonal, though in younger life he wrote some microtonal works.
