Kuznetsovsky Tunnel () is a railroad tunnel on the Baikal Amur Mainline (BAM), on the Sikhote-Alin mountain range in Khabarovsk Krai, Russia. The tunnel, as well as the Kuznetsovsky Pass it provides access to, and a nearby railway station, are all named after Arseny Kuznetsov, a construction engineer who found the suitable location for the railroad, but died during the construction of the tunnel.
