Ussurisky Nature Reserve ( Ussuriyskiy zapavyednik) (also Ussuriysky; V.L. Komarov Reserve) is a Russian 'zapovednik' (strict nature reserve) that protects one of the remaining virgin mixed deciduous-conifer forests in the Primorsky (Maritime) region of the Russian Far East. The mountainous terrain is located on a southern spur of the Sikhote-Alin Mountains, in the upper reaches of the Komarovka River, about 50 km northeast of the city of Vladivostok. The reserve is named after Vladimir L. Komarov, an important early botanist and early explorer of the Primorsky region. The Ussursisky Reserve is situated in the Shkotovsky District of Primorsky Krai.
