Emocapella (a portmanteau of emo and a cappella) is a collegiate a cappella group at the George Washington University, formerly all-male but co-ed since 2010. Emocapella was founded in October 2001 by Eric Denman and Dan Riesser, GW sophomores at the time, who wanted to form a group that purposefully deviated from traditional a cappella. The group's first performance was in December 2001, opening for another GW a cappella group, the Vibes. They were invited by Taking Back Sunday in December 2002 to perform at their opening act.

Emocapella's shows include rock jumps and comedy, and it credits itself with giving the name "Guerillacapella" to doing performances in random spots on campus.
