Walter Charles Mycroft (1890 – 14 June 1959) was a British journalist, screenwriter, film producer and director.
In 1928 he became Literary Adviser and Scenario Editor at the newly founded studio British International Pictures at Elstree, sometimes working with his friend Alfred Hitchcock.
Mycroft was elevated to head of production at Elstree during the 1930s, during which time BIP was reconstituted as the Associated British Picture Corporation.
The company released many films on which Mycroft was credited as producer, with varying levels of actual involvement.
His adopted son, David Rees Mycroft, worked as assistant director on a number of Elstree productions.
