An on-board communication system includes: an on-board relay apparatus configured to relay message transmission and reception between a plurality of bus communication lines; a plurality of first on-board communication apparatuses is connected to one of the plurality of communication lines; and a second on-board communication apparatus is connected to at least two of the plurality of communication lines. The second on-board communication apparatus transmits, if a specific message is received through one of the connected communication lines, the message through another communication line. The on-board relay apparatus determines whether or not the specific message received through one of the connected communication lines satisfies a predetermined discard condition. The on-board relay apparatus does not relay the specific message if it is determined that the discard condition is satisfied, and transmits the specific message from another one of the communication lines if it is determined that the discard condition is not satisfied.
