Sir Percy Clarke Hull (27 October 1878 in Hereford, England – 31 August 1968 in Farnham Surrey) was an English organist and composer who revived the Three Choirs Festival during his time as organist of Hereford Cathedral from 1918 to 1949. A friend of Edward Elgar (who dedicated the fifth of his Pomp and Circumstance Marches to him) and Ralph Vaughan Williams, he was involved in the first performance of Vaughan Williams' Two Hymn Preludes and Prelude and Fugue in C minor for Orchestra.
