Beach Fossils is an American indie rock band from Brooklyn, New York, formed in 2009. They are currently signed to Bayonet Records, having previously been signed to indie label Captured Tracks. The group's live band currently includes founder Dustin Payseur (vocals, guitar), Jack Doyle Smith (bass), Tommy Davidson (guitar), and Anton Hochheim (drums). They are known for their lo-fi, atmospheric sound, confessional and nostalgic lyrics, and Payseur's laid-back vocal style.

Payseur originally conceived the project in late 2008 when he moved to New York City after leaving school in his home state of North Carolina. To date they have released four studio albums, including their eponymous debut album (2010), Clash the Truth (2013), Somersault (2017), and Bunny (2023), as well as one EP titled What A Pleasure (2011). Beach Fossils, along with fellow Captured Tracks label mates DIIV, Wild Nothing, and Mac DeMarco, are considered forerunners in the lo-fi dream pop sound that grew out of the underground indie scene in the 2010s.
