Ian Lancaster Fleming (28 May 1908 – 12 August 1964) was an English author, journalist and naval intelligence officer who is best known for his James Bond series of spy novels. Fleming came from a wealthy family connected to the merchant bank Robert Fleming & Co., and his father was the Member of Parliament for Henley from 1910 until his death on the Western Front in 1917. Educated at Eton, Sandhurst and, briefly, the universities of Munich and Geneva, Fleming moved through several jobs before he started writing.

While working for Britain's Naval Intelligence Division during the Second World War, Fleming was involved in planning Operation Goldeneye and in the planning and oversight of two intelligence units, 30 Assault Unit and T-Force. His wartime service and his career as a journalist provided much of the background, detail and depth of the James Bond novels.

The James Bond series focuses on a fictional British Secret Service agent created in 1953 by writer Ian Fleming, who featured him in twelve novels and two short-story collections. Since Fleming's death in 1964, eight other authors have written authorised Bond novels or novelizations: Kingsley Amis, Christopher Wood, John Gardner, Raymond Benson, Sebastian Faulks, Jeffery Deaver, William Boyd and Anthony Horowitz. The latest novel is Trigger Mortis by Anthony Horowitz, published in September 2015. Additionally Charlie Higson wrote a series on a young James Bond, and Kate Westbrook wrote three novels based on the diaries of a recurring series character, Moneypenny.

The character has also been adapted for television, radio, comic strip, video games and film. The films are the longest continually running and the third-highest-grossing film series to date, which started in 1962 with Dr. No, starring Sean Connery as Bond. As of 2016, there have been twenty-four films in the Eon Productions series. The most recent Bond film, Spectre (2015), stars Daniel Craig in his fourth portrayal of Bond; he is the sixth actor to play Bond in the Eon series. There have also been two independent productions of Bond films: Casino Royale (a 1967 spoof) and Never Say Never Again (a 1983 remake of an earlier Eon-produced film, Thunderball).

The Bond films are renowned for a number of features, including the musical accompaniment, with the theme songs having received Academy Award nominations on several occasions, and two wins. Other important elements which run through most of the films include Bond's cars, his guns, and the gadgets with which he is supplied by Q Branch. The films are also noted for Bond's relationships with various women, who are sometimes referred to as "Bond girls".
