The 1972–73 Shell Shield season was the seventh 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 6 January to 1 March 1973.

Five teams contested the competition – Barbados, the Combined Islands, Guyana, Jamaica, and Trinidad and Tobago. Guyana and Trinidad and Tobago were both undefeated, either winning or drawing all of their games, but Guyana finished with more points, claiming their maiden title. Jamaican batsman Maurice Foster led the tournament in runs for a second consecutive season, while Guyanese off-spinner Lance Gibbs was the leading wicket-taker.
