The Ohio University Marching Band is the 235-member marching band at Ohio University in Athens, Ohio.

Nicknamed the "Marching 110," referring to the original number of members in the band, the Ohio University Marching Band is known around the world for its unique marching style and choreographed dance moves. Founded in 1923, the OUMB has performed over 40 NFL halftime shows, at NYC's Carnegie Hall, in three Macy’s Thanksgiving Day Parades, the Pasadena Tournament of Roses Parade, and internationally in Canada, Ireland, Italy and France. Today, the number "110" symbolizes the 110% effort expected of its members during each and every rehearsal and performance.
