Only Santa Knows is the sixth studio album by Delta Goodrem and her first full-length Christmas album, released on 13 November 2020 through Sony Music Australia. The album features two original tracks and 11 covers, including Silent Night with Gurrumul — a recording made in 2014. In 2021, the album was reissued as a deluxe edition with four additional tracks.

The release came as a surprise with no prior announcement. Goodrem later explained the idea took shape mid-year: she grabbed her Christmas decorations, took them to the studio, and started getting into the spirit — hoping the music would bring joy regardless of everything going on in the world.
