Daniël Muller (born 11 August 1969) is a Dutch former footballer who played as a midfielder.

Born in Amsterdam, Muller played youth football with local AFC Ajax, making his senior debuts with FC Barcelona's reserves in Segunda División. During his spell in Spain, first-team manager Johan Cruyff was often accused of having purchased the player mainly because he was the fiancé of his daughter Chantal;^[1] the 1988–89 season – his only with the Catalans – ended in relegation for the B's.

Released by Barça Muller return to his homeland and Ajax, playing no games during his only campaign. He then moved to neighbouring Belgium where he spent the next three years, in representation of Standard Liège and K. Boom FC.
