Case Study 01 is the second studio album by Canadian singer and songwriter Daniel Caesar, released on June 28, 2019, through Golden Child Recordings. It features guest appearances from Brandy, Pharrell Williams, John Mayer, Sean Leon and Jacob Collier. Caesar held a listening party in Los Angeles in the week leading up to the album's release. Along with invited music industry figures, the event was also open to the first 200 guests that arrived. Caesar also teased the album on social media, including with a video of a person walking across a desert set to a "muted keyboard melody" and a quote from scientist J. Robert Oppenheimer.
