Charlie McMahon (born in the Blue Mountains outside Sydney, 1951) is an Australian didgeridoo player. The founder of the group Gondwanaland, McMahon was one of the first non-Aboriginal musicians to gain fame as a professional player of the instrument.

He is also the inventor of the didjeribone, a sliding didgeridoo made from two lengths of plastic tubing and played somewhat in the manner of a trombone (hence its name).
