Deceiver is the third studio album by American indie rock band DIIV. It was released on October 4, 2019 by Captured Tracks. Produced primarily by the band themselves along with producer Sonny Diperri (My Bloody Valentine, Nine Inch Nails), the album was recorded in Los Angeles in March 2019.

This album is the follow-up to 2016's critically acclaimed Is the Is Are. It is also DIIV's first project since frontman Zachary Cole Smith checked himself into "long-haul inpatient treatment" for substance abuse in 2017. Smith's treatment and recovery period are said to have played an important part in the making of Deceiver. Per a statement, Deceiver is described as "the soundtrack to personal resurrection under the heavy weight of metallic catharsis".

Upon release, Deceiver reached number 177 on the US Billboard 200 and received critical acclaim as a drastic departure from DIIV's earlier work.
