"Do Not Forsake Me Oh My Darling" is an episode of the allegorical British science fiction TV series, The Prisoner. It was written by Vincent Tilsley and directed by Pat Jackson and was the fourteenth produced. It was the thirteenth episode to be broadcast in the UK on ITV (ATV Midlands and Grampian) on Friday 22 December 1967 and first aired in the United States on CBS on Saturday 3 August 1968. The episode stars Patrick McGoohan as Number Six and features as Number Two, Clifford Evans. Produced while Patrick McGoohan was in America filming Ice Station Zebra, the writers worked around McGoohan's absence by having Number Six's mind implanted in the body of another man (Nigel Stock), who is then sent out of the Village to help capture a scientist. As a result, McGoohan appears in the episode for only a couple of minutes. The episode title, and the background music heard throughout it, derive from the American song "The Ballad of High Noon" – also called "Do Not Forsake Me, O My Darlin – introduced in the 1952 movie High Noon.

They are unsuccessful. A man referred to only as "Colonel" arrives at the Village and only then learns from a new Number Two that his mission is to trade bodies with Number Six, using Seltzman's system. Number Six had been the last agent to have contact with Seltzman. After the swap, Number Six (now in the Colonel's body, and retaining only his pre-Village memories) awakens in his old London apartment and soon sees an unfamiliar face in his mirror. His fiancée arrives and, of course, fails to recognise him. He prudently restrains himself from enlightening her. Despite the shock, he realises what has been done to him, maintains his cool, and sets about to regain his own body. After a visit to his former superiors (the most senior of them, Sir Charles Portland, previously seen in the teaser) avails him
