Waterlow & Sons Ltd. was a British security printing firm known for many years as a producer of stamps for many countries.

On January 9, 1961, its stamp printing operation was taken over by De La Rue & Co. Ltd., another of Britain's famous security printing firms.

Waterlow had printed the first British Commonwealth Giori-printed stamps when it produced Jamaica's Postal Centenary issue of January 4, 1960.

In 1940-41, when the facilities of the De La Rue had been destroyed by German Terror bombing, Waterlow had taken over the perforation of certain stamps for New Zealand, gauging 12, 14, and 14x15, creating the so-called "Blitz Perforations."
