Ian F. Mosley (born 16 June 1953, Paddington, London, England) is a drummer in the progressive rock band, Marillion.
Mosley joined the band in 1984 after a long search for a replacement of Mick Pointer, who had been fired in 1983. Mosley had previously, among others, played with former Genesis guitarist Steve Hackett, both on two of his solo studio albums and on tour. He is still a member of Marillion to this day.
