LiveSOS is the first live album by Australian rock band 5 Seconds of Summer, which was released on 15 December 2014. The album consists of 14 live tracks from the band's debut album 5 Seconds of Summer and EP She Looks So Perfect, and a studio mix of "What I Like About You". There's also two bonus tracks, a live version of "Don't Stop" and Kiss Me Kiss Me as iTunes and Target exclusives respectively. To promote the album, the studio version of "What I Like About You" will be serviced to contemporary hit radio in December 2014 as the lead single from LiveSOS.

On 22 November, the band announced through various social networks, and later, through the official website that they would release a live album, featuring songs from their debut album 5 Seconds of Summer, and their EPs. This is the band's first live album and follows their debut studio album released earlier in 2014. On the album, they commented, "Playing live has been something we have been the most passionate about from the beginning. All we want is for our fans to come to the shows, rock out and have one of the best times they've ever experienced. Also when a room is full of you guys from all different walks of life, you can let it go when you come to the shows and be free to be yourself. Our live album 'LIVESOS' is now available to preorder on iTunes or our webstore in the USA, Canada & Mexico. Everywhere else can from midnight this Sunday 23 October. It has 15 tracks recorded in different venues around the world! Anyways we love you, this is us live... You rule!"

The 16 live tracks (including bonus tracks) were all recorded throughout 2014 concerts given by the band, during their headline shows in Europe, North America, and Australia.
