The 1966–67 Shell Shield season was the second edition of what is now the Regional Four Day Competition, the domestic first-class cricket competition for the countries of the West Indies Cricket Board (WICB). The tournament was sponsored by Royal Dutch Shell, with matches played from 8 February to 3 April 1967.
Six teams contested the tournament – Barbados, British Guiana, Jamaica, the Leeward Islands, Trinidad and Tobago, and the Windward Islands. However, the Leeward and Windward Islands both played fewer matches than the other teams, and the results from their matches did not count towards the title. For a second season running, Barbados were undefeated, winning three matches and drawing the other to claim a second consecutive title. Barbadian batsman Peter Lashley led the tournament in runs, while his teammate Rawle Brancker and Jamaican bowler Rudolph Cohen led the tournament in wickets.
