Terney (Russian: Терне́й) is an urban locality (an urban-type settlement) and the administrative center of Terneysky District of Primorsky Krai, Russia, located on the coast of the Sea of Japan on a small bay of the same name.

It was here that the French explorers became convinced that the coast visited by Maarten Gerritsz Vries in the Castricum in 1643 (i.e., in fact, the east coasts of Hokkaido and Sakhalin) was not the mainland, since they were now at the same latitude as the Dutch had been a century and a half before, but the location looked entirely different.

La Perouse's sailors were impressed with good fishing in the area.

Due to the influence of the cold Oyashio Current summers are up to 6 °C or 10.8 °F cooler than in Harbin, and that cold current produces a marked seasonal lag, so that September is on average warmer than June.

Despite the fairly heavy rainfall due to orographic influences from mountains near the Pacific, Terney is much sunnier than nearby localities on the Sakhalin Island.
