Riley Breckenridge (born January 5, 1975) is the drummer for experimental hardcore band Thrice. The older brother of Thrice bassist Eddie Breckenridge, Riley joined Thrice during the early days of the band on the recommendation of Eddie.

Breckenridge says that Thrice tries to "incorporate elements of all the music we listen to. Whether it's metal or punk or hardcore or jazz, or just like straight up rock or mellow kinda indie rock." He also plays guitar and has written parts for some Thrice songs, although the band has not been specific about his writing credits. Breckenridge says that drummer Dave Grohl and the group Radiohead have been major influences on his music.

Breckenridge plays C&C Drum & Percussion instruments. He also uses Vic Firth drum sticks, Zildjian cymbals, Remo drumheads, and Drum Workshop hardware and pedals. Breckenridge, along with Morningwood lead singer Chantal Claret, writes a monthly advice column in Alternative Press magazine. The column is titled "Battle of the Sexes" though their comments are often similar.
