Gibbons Stamp Monthly (GSM) is a British philatelic magazine which can trace its roots back to 1890.

GSM is published by the famous stamps and collectables firm of Stanley Gibbons and each issue includes updates to their various catalogues.

[2] The new Journal lasted until September 1927, when it was replaced by Gibbons Stamp Monthly from October 1927.

Post-war paper rationing and electricity cuts were also a problem, and the staff sometimes had to work by candlelight.

In 1967 an American sister journal, the Gibbons-Whitman Stamp Monthly, was introduced but this ceased publication in 1969.
