The Yale Precision Marching Band (affectionately known as the YPMB, or more simply The Band, for short) is the official marching band of Yale University. It is a scatter band (what some peers might call a "scramble band"), as distinct from university marching bands that emphasize precise movements and geometric field formations. Band members refer to themselves as "The Members Of...", which is derived from their introduction at Yale events.

Aside from Director Thomas C. Duffy and Business Manager Stephanie Theodos Hubbard, the band is largely student-run.

In October 1985, six YPMB members were suspended after dropping their pants at halftime during the Yale-Holy Cross game. Only one week earlier, the band was forbidden by West Point officials from performing its halftime show during the Army-Yale game for the script's insinuation that certain government officials were communists. The following season, in the Yale-Army game at New Haven, the YPMB took the unusual step of marching in straight lines for several minutes before breaking into its usual scatter formations. (NYT 10/7/86, B4) Before the band left the field, members removed their blue blazers on the field, spelling out "USA."

The repertoire also includes scores or hundreds of songs arranged by students.
