A vehicle noise canceller includes a road surface condition observation unit, a speaker, and an operation controller. The road surface condition observation unit is configured to observe road surface conditions in a traveling direction of a vehicle. The speaker is configured to generate a canceling sound for canceling road noise entering a vehicle cabin of the vehicle. The operation controller is configured to control the canceling sound generated from the speaker on a basis of information received from the road surface condition observation unit.
