2016–17 Regional Four Day Competition

The Regional Four Day Competition, formerly known as Shell Shield and Carib Beer Cup, is the first class cricket competition in the West Indies, it is administered by the West Indies Cricket Board. In the 2013-2014 season the winner of the tournament was awarded the WICB President's Trophy while the winners of the knockout competition were awarded the George Headley/Everton Weekes trophy. In a few previous seasons the winners of the tournament were awarded the Headley/Weekes trophy.

The competition is contested between seven Caribbean teams and, on occasion, touring sides from other countries. Four of the Caribbean teams, Barbados, Guyana, Jamaica and Trinidad and Tobago, come from individual countries while two teams, the Leeward Islands and the Windward Islands, which previously competed together as the Combined Islands, are each from multiple countries and territories. Since the 2007–08 season the Combined Campuses and Colleges cricket team (CCC cricket team) have been included in the competition, but in July 2014, it was announced by the WICB that the CCC cricket team was to be excluded from the upcoming 2014-15 Regional Four Day competition as part of a series of changes adopted based on the recommendations made in a report presented by Richard Pybus, WICB's director of cricket, in March 2014.

The current structure of the tournament is a round-robin league system followed by semi-finals and a final. In the past there was no knock-out stage and it was possible for the winners to share the trophy. Barbados, the current champions, have won the most titles, with twenty (and one shared), while Jamaica have won the most consecutive titles (five).
