Gawain Peter Briars (born 4 April 1958) is a sportsman and lawyer in the United Kingdom.

Briars learnt to play squash at Gresham's School, Holt, which he attended from 1968 to 1976, and became a professional squash player on leaving school at the age of eighteen, continuing as a professional until 1989.

He won titles in the USA, France, Canada, New Zealand, Australia, Monte Carlo, Singapore and Malaysia, and was President of the world Professional Squash Association from 1985 to 1987.

[1] On retiring from the professional sport in 1989, Briars went to University College, Cardiff to study law, and subsequently qualified as a solicitor in 1994.

With effect from 1 October 1999, he was appointed as Executive Director of the Professional Squash Association (PSA), succeeding John Nimick, of Boston, USA, and commented: "This represents a wonderful move for me away from the legal profession, but not without relinquishing the invaluable knowledge and experience I have gained whilst practising in commercial law.
