"Yip, Yip, Yaphank" is the name of a musical revue composed and produced by Irving Berlin in 1918 while he was a recruit during World War I in the United States Army's 152nd Depot Brigade at Camp Upton in Yaphank, New York. After its Broadway run, the show was not performed until Longwood High School performed the show for its 100th anniversary.

In July 1918, "Yip, Yip Yaphank" had a tryout run at Camp Upton's little Liberty Theatre, before moving on to Central Park West's Century Theatre in August. The show was typical of revues and follies, featuring acrobatics, dancers, jugglers, and also featured a demonstration by Lightweight Boxing Champion Benny Leonard. Included with the performances were military drills choreographed to music by Berlin.

"God Bless America" was originally written for the play but not included in this play. It was included in the sequel to "Yip Yip Yaphank" entitled "This is the Army" in 1943
