K-329 Belgorod (Russian: БС-329 «Белгород») is a modified design of the Oscar II class (NATO designation) Russian nuclear submarine. It was laid down in July 1992 as a Project 949A cruise missile submarine, NATO designation Oscar II class. It was redesigned and the partly built hull was reconfigured as a special operations vessel, able to operate unmanned underwater vehicles. The vessel was relaid in December 2012. Due to chronic underfunding, its construction was suspended, then resumed at a low rate of progress before the ship was redesigned to become a unique vessel — the first Russian fifth-generation submarine, according to the Ministry of Defence.

The K-329 Belgorod, along with the Status-6 Oceanic Multipurpose System, was one of the latest weapons systems presented by Russian President Vladimir Putin during his annual speech in March 2018. It tested at sea in 1H2022 and was commissioned by the Russian Navy in July 2022. The submarine was delivered to the Russian Navy on 8 July 2022.

In light of the decommissioning of the last Typhoon-class submarine in 2023, the Belgorod is the world's largest operational submarine.

The Belgorod will reportedly be the first submarine to utilize the Status-6 Oceanic Multipurpose System.
