Alun Morgan (born 1928, Pontypridd, Wales) is a British jazz critic and writer.
Morgan became interested in jazz as a teenager during World War II, and Charlie Parker became a significant influence on him in the late 1940s. Morgan began to write on jazz from the early 1950 for Melody Maker, Jazz Journal, Jazz Monthly and Gramophone, and for 20 years from 1969 a weekly jazz column in a local Kent newspaper. Over his writing career he completed liner notes for over 2,500 albums, initially for Vogue Records. From 1954 he contributed to music programmes for BBC Radio.
Morgan is the author of a book on modern jazz in England and the co-author of several books on jazz records. He has lectured on jazz at the Guildhall School of Music and Drama and the Royal Academy of Music in London.
In addition, until 1991 he was a full-time architect. Shortly after retiring from his other occupation, Morgan emigrated to Australia.
