Michaela Tabb (born 11 December 1967, in Bath, England) is a Scottish snooker and pool referee, notable for establishing significant milestones for women officials in professional snooker.
She began refereeing professionally on the pool circuit in 1997, and has officiated at top pool tournaments such as the WPA World Nine-ball Championship and the Mosconi Cup. After qualifying in 2001 to referee on the professional snooker tour, she went on to become the sport's highest profile female referee. During her 14 years on the tour, she became the first woman to officiate at a professional ranking snooker tournament (2002), the first woman to referee a ranking tournament final (2007), and the only woman ever to have refereed the World Snooker Championship final (2009 and 2012).
Her professional snooker refereeing career came to an end when she abruptly left the tour in March 2015. She subsequently brought a court case against the sport's governing body, alleging sex discrimination, unfair dismissal, and breach of contract. An out-of-court settlement was reached in September 2015, under which Tabb was paid an undisclosed sum.
