"Crawl Back In" is a song by American rock band Dead By Sunrise, which consists of Linkin Park lead singer Chester Bennington, as well as the band members of Julien-K. It is the first single and the second track from their debut studio album, Out of Ashes. It was released through iTunes on August 18, 2009. An official music video for the single was released on September 8, 2009, directed by P.R. Brown.

The song talks about Bennington's past problems with alcohol addiction, similar to many of the lyrical themes on Linkin Park's debut album Hybrid Theory. Bennington has stated in an interview with MTV that "It's a song about questioning your authenticity. I do that every once in a while; I wonder how many of my own thoughts are really my own, and how much influence do the people around me have on the person I am." MTV's James Montgomery described the song as "plenty dark" but "not pitch-black", as well as saying "Lyrically, the song details Bennington's slow climb back into the light — a climb that started with some serious self-discovery."

The song was rumored to be on the Transformers: Revenge of the Fallen soundtrack, which also features Linkin Park's "New Divide". Bennington later confirmed the rumor, however Bennington said he decided not to include it. The song was used as the theme song for TNA Bound For Glory 2009 PPV. The song was recorded live during Linkin Park's encore at the Sonisphere Festival 2009 in Knebworth and released free via e-mail for those who had previously downloaded the Sonisphere EP, which featured other artists who performed at the festival: Mastodon, The Used, Avenged Sevenfold and Taking Back Sunday.
