Dry and Thirsty is a 1920 American silent comedy film, directed by Craig Hutchinson. It is a satire of the Prohibition era in the United States. The film spoofs former Secretary of State William Jennings Bryan, who campaigned for Prohibition; the character is dubbed "William Allways Tryan."

The stars, Billy Bletcher and Vera Reynolds, were a popular comedy duo in "Gayety Comedies". At the time of Dry and Thirsty's release, Gayety also released Twin Bedlam, another Bletcher/Reynolds comedy.

This was the first film for vaudeville actor Tom Dempsey, appearing under the stage name "John Dempsey". He later appeared in The Bush Leaguer (1927), Nifty Numbers (1928) and other Educational Pictures comedies, and more than thirty Mack Sennett comedies in the 1930s.
