The invention discloses a multi-user resonant optical communication system and method based on optical code division multiple access. The system comprises a base station and a mobile terminal, and the mobile terminal comprises transceivers located at different users; a resonant cavity is formed between the base station and each transceiver; the base station comprises a first reflex reflector, a first gain medium, a first electro-optical modulator, a first beam splitter, a first photoelectric detector, a first signal processing board, a second photoelectric detector, a first synchronization device and a second signal processing board; and each transceiver comprises a second reflex reflector, a second gain medium, a second beam splitter, a third photoelectric detector, a coupler, a third signal processing board, a second synchronizer and a second electro-optical modulator. According to the invention, through the design of a coding and decoding structure, a plurality of users can communicate with the transmitter
