A '''divemaster''' (DM) is a role that includes organising and leading recreational dives, particularly in a professional capacity, and is a qualification used in many parts of the world in recreational [[scuba diving]] for a diver who has supervisory responsibility for a group of divers and as a dive guide. As well as being a generic term, 'Divemaster' is the title of the first professional rating of many [[List of diver certification organizations|training agencies]], such as [[Professional Association of Diving Instructors|PADI]], [[Scuba Schools International|SSI]], [[Scuba Diving International|SDI]], [[National Academy of Scuba Educators|NASE]], except [[National Association of Underwater Instructors|NAUI]], which rates a NAUI Divemaster under a NAUI Instructor but above a NAUI Assistant Instructor. The divemaster certification is generally equivalent to the requirements of [[International Organization for Standardization|ISO]]&nbsp;24801-3 [[Dive Leader]].<ref name="ISO24801-3" />

The British Sub-Aqua Club ([[British Sub-Aqua Club|BSAC]]) recognizes several agencies' divemaster certificates as equivalent to BSAC Dive Leader, but not to BSAC Advanced Diver.<ref name="bsac-recognition" /> The converse may not be true.<ref name="idc" />

The certification is a prerequisite for training as an instructor in [[recreational diving]] with the professional agencies except [[National Association of Underwater Instructors|NAUI]], where it is an optional step, because of the different position of the NAUI Divemaster in the NAUI hierarchy.<ref name="NAUI leadership arch" />
