The Society for the Suppression of Speculative Stamps (S.S.S.S.) was a short-lived and ill-fated attempt by philatelists before 1900 to suppress the issue of stamps designed mainly for sale to collectors.

The society was formed on 6 May 1895 and lasted until about 1897 when it broke up due to the failure of dealers and collectors within its ranks to boycott speculative issues.^[1]

The society was supported by the Royal Philatelic Society London and the American Philatelic Society.
