An in-vehicle communication system is provided with an in-vehicle device group including four or more in-vehicle devices. A specific in-vehicle device group, which is a part of the in-vehicle device group and includes three or more specific in-vehicle devices being the in-vehicle devices, circulates a specific target packet. A first in-vehicle device being the specific in-vehicle device performs a detection process of detecting abnormality of a specific in-vehicle device, other than the first in-vehicle device, in the specific in-vehicle device group, based on a reception state of the target packet.
