An in-vehicle communication system comprises a plurality of in-vehicle relay devices, each including a plurality of first connection units, an in-vehicle communication device connected to each one of the first connection units, a plurality of second connection units to which another one of the in-vehicle relay devices is connected, and a relay processing unit that relays messages between the in-vehicle communication devices connected to the first connection units and the in-vehicle relay devices connected to the second connection units, wherein two of the in-vehicle relay devices are connected to one another via two or more communication lines. The in-vehicle relay devices each include a storage unit that stores relationships between identification information attached to messages received via the first connection units and the second connection units corresponding to transmission destinations of the messages, and updates the relationships according to a communication status of communication via the second connection units.
