Neck Deep are a Welsh pop-punk band from Wrexham, formed in 2012. They released a pair of EPs, Rain in July (2012) and A History of Bad Decisions (2013), before signing with Hopeless in August 2013.

Neck Deep was founded after vocalist Ben Barlow met former lead guitarist Lloyd Roberts; the pair posted a song ("What Did You Expect?") online under the name Neck Deep. The song soon gained attention online, resulting in the addition of rhythm guitarist Matt West, drummer Dani Washington/Abasi, and bassist Fil Thorpe-Evans.

Following the release of their debut album Wishful Thinking in January 2014, the band became a full-time project, with the band members leaving their jobs and/or dropping out of university courses. Shortly after the release of their second album Life's Not out to Get You in August 2015, Roberts left the band due to allegations of sexual misconduct (which he was subsequently found to have no case to answer), and Sam Bowden (formerly of Climates and Blood Youth) joined in his place. The group's third album The Peace and the Panic was released August 2017, and debuted at No. 4 on the US Billboard 200. In September 2018, Thorpe-Evans left the band to pursue a solo career as a producer. In 2019, the band embarked in a summer tour with Blink-182 as the opening act. By February 2020, the band added longtime collaborator and bassist Seb Barlow as an official member; later that month, they also revealed an app with a variety of multimedia regarding the announcement of their fourth album, titled All Distortions Are Intentional, released 24 July 2020. Their self-titled fifth album was released on 19 January 2024.
