The invention discloses a rotatable vehicle interior dome lamp. The rotatable vehicle interior dome lamp comprises a rear cover plate, a panel fixedly installed to the rear cover plate, and a circuitboard assembly and a rotary mask that are installed between the panel and the rear cover plate. The rotary mask comprises a rotating ball head and a rotating head used for operating the rotary mask. The panel is provided with an installation opening, thus guaranteeing that the rotating head and a part, connected to the rotating head, of the rotary mask are exposed out of the panel. And after the panel is mounted on the rear cover plate, a guide chute for the rotating ball head to slide is formed. The rotary mask with the rotating ball head can rotate along a connecting line of the ball centerof the rotating ball head and the ball center of the rotary mask, and the rotary mask can do arc motion along the guide chute, therefore the light-emitting area of the vehicle interior dome lamp can be changed in a large range.
