Hank Martin, an American mechanic, is knocked out and wakes up in the land of King Arthur. Here he finds romance with Alisande la Carteloise and friendship with Sir Sagramore. Unfortunately, the heroic Hank also incurs the hatred of both Merlin and Morgan le Fay. While Hank persuades King Arthur, an aged, semi-perpetual, cold-in-the-nose invalid, to tour his kingdom in disguise to see the true, wretched condition of his subjects, Merlin and Morgan plot to usurp his throne. When Hank tries to stop them, he is returned to his own time. Heartsick over losing the woman he loves, he goes on a tour of a British castle. Its owner, Lord Pendragon, sends him to see his niece, who looks just like Alisande.
A highlight of the film is the scene in which Hank Martin teaches the court musicians how to "jazz up" the medieval music they are playing. Perhaps the best-known song from the score is "Busy Doing Nothing", which Hank, Sir Sagramore and the King sing when they are strolling through the woods pretending to be peasants. The cast made separate recordings of the songs used in the film for Decca Records in December 1947 and these were issued as a 78rpm album set. Crosby's songs were also included in the Bing's Hollywood series.

The film opened on April 7, 1949 at Radio City Music Hall in New York City and, together with the Music Hall's annual Easter pageant and stageshow, generated the Music Hall's biggest four-day Easter gross at the time, grossing $146,000 in its first week. The following week, with children out of school and the theatre opening at 7:45 a.m. to enable six showings a day, it grossed a Music Hall record $170,000 and became the number one film in the United States. Contemporary reviews praised Crosby's performance but had mixed assessments about other aspects of the film. Bosley Crowther of The New York Times was positive, writing: "The solid, reliable humors of Mark Twain’s 'A Connecticut Yankee in King Arthur’s Court,' which have already done yeoman service in two films and a Broadway musical show, have been given another going over—with eminently satisfactory results—in Paramount’s new film of the same title, which came to the Music Hall yesterday. And for this we can thank Bing Crosby, primarily and above all, because it is Bing in the role of the Yankee who gives this film its particular charm... But it is still Bing’s delightful personality, his mild surprises and sweet serenities, and his casual way of handling dialogue that makes this burlesque a success. No one in current operation could qualify, we are sure, to play the Connecticut Yankee the way the old Groaner does. Harrison's Reports also liked the film, calling it "A very good romantic comedy" with "numerous situations that will provoke hearty laughter." Edwin Schallert of the Los Angeles Times wrote: "All in all, I would put this picture well up among Paramount's Crosby features as an effort to accomplish something different... It is a pleasantly fabulous excursion in the dream classification, and the cutback to the medieval past is effectively enough introduced in this adaptation of the Mark Twain story."
Variety was not quite so enthusiastic. "Picture wears the easy casualness that's a Crosby trademark, goes about its entertaining at a leisurely pace, and generally comes off satisfactorily. It's not high comedy and there’s little swashbuckling." Richard L. Coe of The Washington Post wrote that the idea was "so promising that it's a shame the picture collapses," explaining, "The early half of the picture accepts Bing's particular brand of easy charm... But social welfare work among the downtrodden peasantry hardly fits into my idea of cheerful musical comedy." John McCarten of The New Yorker wrote that Crosby was "effortlessly amiable," but that the film lacked the wit of the 1931 Will Rogers version and that the songs were inferior to those of the Rodgers and Hart stage musical. In 2008, the American Film Institute nominated this film for its Top 10 Fantasy Films list.
