The 155 mm Creusot Long Tom was a French siege gun (artillery piece) manufactured by Schneider et Cie in Le Creusot, France and used by the Boers in the Second Boer War as field guns.^{[1]: p. 164}

Four guns, along with 4,000 common shells, 4,000 shrapnel shells and 800 case shot were purchased by the South African Republic (informally known as the Transvaal) in 1897. The guns were emplaced in four forts around the country's capital, Pretoria.^[2]
