Animelo Summer Live, abbreviated as Anisama (アニサマ, Anisama), is the biggest annual anime song music festival in Japan hosted by Dwango and Nippon Cultural Broadcasting. Animelo Summer Live has been held every summer since 2005.

Animelo performers are singers and voice actors that specialize in singing anime or game theme songs; however, they also both present and perform new original and tokusatsu songs as well. The performers are not necessarily under the same record label. Animelo has a different theme song for each year, which is sung by all performers in the end of the concert.^{[citation needed]}

More general artists who have performed anime songs have also performed, including Rina Aiuchi, m.o.v.e, AAA, Shoko Nakagawa, Kenji Ohtsuki, Gackt, and Momoiro Clover Z. Due to various copyrights and contracts, some performances belonging to certain record labels have sometimes not been included on the video distributed on DVDs and Blu-Rays. This factored into the lack of a video release for 2005.^{[citation needed]}

Because all music is played live, performs often appear with their band or dancers. Performers who do not have a band appear with a selected "Anisama band."^{[citation needed]}

Starting with Anisama Girl's Night in 2010, there have been many spinoff Animelo events.

The sponsors of the event have been Dwango, Nippon Cultural Broadcasting, Good Smile Company, and Bushiroad.

Note: Personal names are in order by last name first except in cases of band names.

Each CD contains a theme song that was used for that given year.
