Hooray for Our Side is an American ska punk band based in Anaheim, California. The group was founded in 2010 by Nikki Klein, Peter Stoia, and Evan Wohrman, upon their departure from ska outfit Time to Renew. Since 2011, the group's lineup has consisted of guitarist Katon Guinen, drummer Nikki Klein, bassist Veg McCoy, and vocalist Evan Wohrman.

In late 2012, H4OS teamed up with musician/producer Vincent Walker (Suburban Legends, The Littlest Man Band) to record their debut EP, Community Service, named so for the community involvement on the project, which features musicians from local ska punk bands and was funded in part by fans via Kickstarter.
