Ilford Delta is a series of photographic films manufactured by Harman Technology Limited. Delta films are tabular-grain black-and-white films, and originally released in 400 ISO only to compete with Kodak's T-Max film.

Ilford recommends Delta 100 and 400 as replacements for the discontinued Agfa APX100 and APX400 films, respectively. Delta 100 can be used at ISO speeds of 50 to 200.
