Almost Acoustic Christmas is an annual concert run by the Los Angeles radio station KROQ-FM. Like the radio station's other festivals, it is a festival organized by KROQ-FM to raise money for a charity, and promotes a variety of rock music from the radio station's format, including alternative, indie, punk, pop, dance and hard rock/heavy metal. Since its first show in 1989, the Acoustic Christmas has traditionally been held either the second or third weekend of December, with the exception of a three-year hiatus between 2019 and 2022 due to the COVID-19 pandemic.
