The present invention provides a bicycle seat post height adjustment mechanism. When said bicycle seat post height adjustment mechanism is in a state of locking, said lower valve packing ring may block said lower valve port, and moreover, based on demands, said upper valve packing ring is allowed selectively to block said upper valve port or to be away from said upper valve port so as to stay on top of said upper valve port. Thus, said pin is driven to axially move down so as to enable said seat post to make fine adjustment, stepless adjustment or stepped adjustment in height; moreover, said seat post may self-return to the assigned position (upper position, middle position or lower position) to prevent the height of the seat from altering.
