A vehicular active noise reduction system includes a first microphone and first speaker disposed in a front-seat space, a second microphone and second speaker disposed in a back-seat space, and an active noise reduction device that performs control to output cancellation sound, to reduce noise in a cabin, from the first speaker and second speaker. When generating a first composite audio, the active noise reduction device removes audio components belonging to a frequency band relating to a second cancellation sound from audio collected by the first microphone, and when generating a second composite audio, removes audio components belonging to a frequency band relating to a first cancellation sound from audio collected by the second microphone.
