'Twas the Night Before Christmas is a 1974 animated Christmas television special produced by Rankin/Bass Productions that features Clement Clarke Moore's famous 1823 poem A Visit from St. Nicholas, the opening line of which is the source of the title of this animated special. The special first originally aired on CBS on December 8, 1974, and the network aired it annually until 1994, when The Family Channel (now Freeform) took over its syndication rights. AMC took over syndication rights for the special in 2018.

Although the opening credits mention "told and sung by Joel Grey", it is really narrated by George Gobel, as there is more emphasis on the point of view of Father Mouse, with Moore's poem read by Grey as a secondary plot.
