Kuznetsovsky Tunnel (Russian: Кузнецовский туннель) 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.

[1] That old tunnel was built during World War II and completed by 1945.

The construction of the new tunnel will lead to a significant increase in freight traffic on the Eastern Baikal Amur Mainline, which connects Komsomolsk-on-Amur with the sea ports of Vanino and Sovetskaya Gavan.

The total cost of the project is estimated to be 59.8 billion rubles.
