The Rotary Club of Grand Cayman (RCGC) was chartered by Rotary International on November 8, 1965.

When RCGC was formed there was no Rotary District in which the Cayman Islands could be placed. Soon after, however, District 404 was created, and later it was renamed District 4040 and then District 7020, as it is currently named. District 7020 encompasses 57 clubs and is part of Rotary Zone 34.

RCGC is the oldest Rotary club in the Cayman islands, and it has sponsored all of the others, which are the Rotary Club of Cayman Brac (chartered in 1981), the Rotary Club of Grand Cayman Central (chartered in 1986), the Rotary Club of Grand Cayman Sunrise (chartered in 2002), and Rotary Club of Grand Cayman Sunset (chartered in 2023).

The Rotary Club of Grand Cayman has provided seven District Governors. They are:

  1. Arthur Hunter (1982-83)
  2. John Furze (1988-89)
  3. Richard Harris (1992-93)
  4. Robert (Bobby) Bodden (1999-00)
  5. Alastair Paterson (2006-07)
  6. Jeremy Hurst (2013-14)
  7. David Kirkaldy (2023-24).

Major projects undertaken by RCGC have included the construction of the Bonaventure Boys Home and the Frances Bodden Girls Home, whilst major annual events organised by the club include the Batabano Carnival, the Fishing Tournament, the Boxing Day Lunch for Senior Citizens, and the annual Christmas Tree Lighting Ceremony at Heroes' Square. In addition, the RCGC has provided a kidney dialysis machine, a learning booth and 2 mobile dental units. Other projects undertaken by the Club have been the Meals on Wheels programme, painting the Pines retirement home; donating an incubator to the hospital; raising funds for the RI PolioPlus Programme; sponsoring a soccer training camp for boys; and supplying computers for the Deaf School in Mandeville, Jamaica. In all, the Club has raised and donated almost two million dollars.

In the 54 years since its establishment, the Rotary Club of Grand Cayman feels that it can be justly proud of its achievements as a service club, both locally and internationally. Its International and District achievements have included its contribution to the Rotary Foundation, as evidenced by this Club having the largest number of Paul Harris Fellows - 183 - of any club in the 7020 District and the many District awards and Citations which the Club has been presented with over the years.

With approximately 100 members, the membership of the Club is a fair representation of the business community in Cayman with members ranging in age from their 20s to their 80s.
