The Spalding Gentlemen's Society is a learned society based in Spalding, Lincolnshire, England, concerned with cultural, scientific and antiquarian subjects. It is Britain's oldest such provincial body, founded in 1710 by Maurice Johnson (1688–1755) of Ayscoughfee Hall. Membership is open to anyone aged 18 or over: the term "gentlemen" in the title is historical – there is no discrimination between men and women. Its Grade II listed museum in Broad Street, Spalding, was designed by Joseph Boothroyd Corby and opened in 1911; additions to the building ensued in 1925 and 1960. The carved outside panels were by Jules Tuerlinckx of Malines, a Belgian refugee in the First World War.
