Sir Anthony James Allan Havelock-Allan, 4th Baronet (28 February 1904-11 January 2003) was a British film producer.

Havelock-Allan was born at the family home of Blackwell Grange, near Darlington, and was educated at Charterhouse and schools in Switzerland. Before becoming a film producer, he had been a stockbroker, jeweller, record company executive and cabaret-manager.

In 1935, Havelock-Allan joined the short-lived British and Dominions Imperial Studios, producing films with them until the studios burnt down in 1936. After working with her on This Man in Paris, Havelock-Allan married actress Valerie Hobson, on 12 April 1939. In 1943, he founded his own company, Cineguild and in 1945 himself, Noel Coward and Ronald Neame, produced David Lean's Brief Encounter. Havelock-Allan also worked with Neame on Lean's Great Expectations in 1946 and was nominated for both films for the Academy Award for Writing Adapted Screenplay. He also fonded Constellation Films in 1947 and co-founded British Home Entertainment with Lord Brabourne in 1960.

On 12 April 1939 Havelock-Allan married his first wife, the actress Valerie Hobson (later to marry John Profumo), they divorced in 1952. On 26 June 1979 he married Maria Theresa Consuela Sara Ruiz de Villafranca, a daughter of the former Spanish Ambassador to Chile and Brazil. In 1975, he had succeeded to his childless brother's baronetcy and on his own death in 2003, aged 98, his title passed to his son, Mark.

Anthony Havelock-Allan produced some of the best known and critically acclaimed films of the British cinema including In Which We Serve (1942), Brief Encounter (1945), Blithe Spirit (1945) and Great Expectations (1946). The films were commercial triumphs for Two Cities and Cineguild production companies making Havelock-Allan one of the most influential producers in the British cinema. He is also remembered for two films he made starring his then wife Valerie Hobson, the melodrama Blanche Fury (1947) and The Small Voice (1948) which introduced Howard Keel to the screen. Born at Blackwell Manor, near Darlington, England, Havelock-Allan was educated at Charterhouse. Having turned down a career in the Army he worked as a stockbroker and a nightclub manager before becoming a casting director. In the early 1930s he spent two years producing 'quota quickies', small films made for Paramount-British which were made in six days. Although the films were low budget they did provide a valuable training ground for directors such as Michael Powell and cameraman Ronald Neame. Many of them also featured then unknown actors such as Rex Harrison and Margaret Rutherford. In 1942 he produced one of the most famous of all flag waving war films, Noel Coward's In Which We Serve, co-directed by Coward with David Lean. The naval epic was a thinly disguised saga of the maritime exploits of Lord Louis Mountbatten and included definitive performances from Bernard Miles, Celia Johnson and John Mills. A year later he formed the creative partnership of Cineguild Productions with Noel Coward, David Lean and Ronald Neame which made This Happy Breed (1944), Blithe Spirit (1945) and Brief Encounter (1945), an adaptation of Coward's play, Still Life. Cineguild broke up in 1949 and Havelock-Allan formed Constellation Films, an independent production company financed by the Rank Organisation. With the company he made Paul Gallico's Never Take No For An Answer (1951). In 1960 Havelock-Alland and Lord Brabourne formed British Home Entertainment, which sought to introduce pay-TV into Britain. The company was sold in 1969 after the closure of a trial service. Havelock-Allan's later films included Franco Zeffirelli's Romeo and Juliet (1968) and David Lean's Ryan's Daughter (1970).
