Secondfest is a music festival which takes place in the Second Life virtual world. Unlike other musical performances on the web which provide audio through individual web pages for listeners to enjoy by themselves, Secondfest offers an on-line community the ability to experience entertainment together, in a large virtual space.

The first Secondfest event was aired in June 2007 and was favorably received by the artists and Second Life users alike. The festival was conceived and produced by the company Rivers Run Red - the metaverse development agency based in London (directed by Justin Bovington) and Sara Linfoot (head of digital partnerships) and Sarah Ellison (head of events) at The Guardian and curated by Sav Remzi of Tirk Records. The event was sponsored by Intel, with an emphasis on the 'power within' This, the first on-line festival of its type, featured artists and arenas from the UK festival circuit. Secondfest was subsequently awarded the AOP (Association of Online Publishers) prize for the 'Innovation' category and The Guardian Achievement Award for 'Innovation in advertising'.
