Sir John Augustus Fitzroy Watts KCMG CBE (1921 or 1922 – 11 May 2015) was a Grenadian dentist, politician and co-founder of the Grenada National Party.
He and his friend, the barrister and civil servant from Carriacou, Herbert Blaize, started the Grenada National Party (GNP).
He was later appointed member of the 1976 Convention Committee of Rotary International and helped the charter of the Rotaract Club of Grenada (on 21 January 1978).
Whilst he was vice chairman of the New National Party (NNP) and head of the Grenada tourist board, Dr. Watts was first appointed a senator on 27 April 1998 (at that time replacing Alphonsus Antoine).
Dr Keith Mitchell mentioned his own successful bid for leadership of the party in 1989, noting that Sir John, unlike many of his peers, was the one person who stated, “let democracy prevail” when he wrested leadership from Mr Blaize, which led to formation of the New National Party.
