Assignment K (also known as Department K) is a 1968 British spy thriller film directed by Val Guest in Techniscope and starring Stephen Boyd, Camilla Sparv, Michael Redgrave, Leo McKern, Robert Hoffmann and Jeremy Kemp.

A British spy has his cover blown, leading to the East German Stasi kidnapping his girlfriend to try to extract information about his double agents' activities.

"[4] The Monthly Film Bulletin wrote: "Routine spy thriller, unimaginatively scripted and directed.

The entirely conventional settings include the inevitable night clubs, expensive hotels and ski slopes (where the travelling matte is much in evidence).

Stephen Boyd is bland and wooden as the toy tycoon/spy; Camilla Sparv has little to do but look alluring; and Leo McKern and Michael Redgrave appear fleetingly and to little effect.
