Rudolph and Frosty's Christmas in July (titled on-screen as Rudolph and Frosty: Christmas in July) is an American-Japanese Christmas/Independence Day film produced by Rankin/Bass Productions, featuring characters from the company's holiday specials Rudolph the Red-Nosed Reindeer (1964) and Frosty the Snowman (1969), among others. It was filmed in Japan using the company's trademark "Animagic" stop-motion animation style. The film was originally a theatrical film released through Avco Embassy Pictures where it ran for only 2-3 weeks and was considered a box office flop. Later that year, the film premiered on television in the US on November 25, 1979, on ABC where it received better status.This was the last Rankin/Bass special to star Billie Mae Richards as Rudolph and Jackie Vernon as Frosty. Mickey Rooney reprised his role as Santa Claus from Santa Claus Is Comin' to Town (1970) and The Year Without a Santa Claus (1974). Additional voices were provided by Red Buttons, Ethel Merman, Alan Sues, and Paul Frees. Shelley Winters and Frees reprised their roles as Frosty's wife Crystal and Jack Frost from Frosty's Winter Wonderland, and Hal Peary reprised his role as Big Ben the Clockwork Whale from Rudolph's Shiny New Year.

This was the final Rankin/Bass special to use Rudolph and Frosty. All other specials and films starring the characters were produced by other companies.
