The Harvard University Band (HUB) is the official student band of Harvard University. The Harvard Wind Ensemble, the Harvard Summer Pops Band, and the Harvard Jazz Bands also fall under the umbrella organization of HUB. Currently, the band plays for all football games as well as home men's and women's ice hockey games. Occasionally it plays at men's and women's basketball games. The uniform for both football games and other formal appearances consists of a crimson wool HUB blazer worn over a white shirt with a black HUB logo tie, black pants, and black shoes. In the early days of the Band, white sailor hats and khaki pants were worn. For hockey games, the band wears a custom Harvard Band hockey jersey, modeled after the home jerseys for men's hockey, which features images of Bertha on the sleeves. Band alumni, known as crusties, maintain strong ties to the HUB, sometimes continuing to act as regular members well after graduating from the university. Illegitimum non carborundum (INC) is the HUB motto. Written correspondence from HUB or HUB members is frequently signed with INC.

Illegitimi non carborundum is a mock-Latin aphorism, often translated as "Don't let the bastards grind you down". The phrase itself has no meaning in Latin and can only be mock-translated.
