James Riley Breckenridge (born January 5, 1975) is the drummer for the band Thrice.

[2] It kind of dawned on me that being 5-foot-9 and having a surgically repaired knee and not being out-of-this-world talented, the cards were stacked against me...I was better off getting a degree and focusing my time on music.

Breckenridge, along with Morningwood lead singer Chantal Claret, wrote a monthly advice column called "Battle of the Sexes" in Alternative Press magazine for nearly 3 years; which was discontinued in the Winter of 2007.

A middle infielder, he redshirted as a freshman and only saw limited action as a sophomore.

After a coaching change at Pepperdine, he transferred to a junior college where he played for a year before giving up baseball to focus on music.
