Khasan (Russian: Хаса́н) is an urban locality (an urban-type settlement) in Khasansky District of Primorsky Krai, Russia.

It is located near the tripoint on the Tumen River where the borders of Russia, China and North Korea converge.

After World War II, the Baranovski-Kraskino line was continued to the border with North Korea, resulting in a total length of 238 kilometers (148 mi).

It has long remained a dead-end: across the Tumen River, which forms the state border, a temporary wooden bridge was built, which carried its first working train into Korea in 1952.

Exchange of goods between the Soviet Union and North Korea by rail through the Khasan station began in 1954.

Two years later, Khasan station exports had grown an incredible fourteen-fold and imports sixteen-fold.

To implement the project, the Russian Railways Trading House and the Port of Rajin set up a joint venture.

By the following February, a new dual gauge with the length of 32 kilometres has been laid at the Rajin-Khasan section, complete overhaul of 20 kilometres of the tracks has been made, railroad switches and tracks were installed, a number of stations reconstructed, the work in the tunnels was started, trunk telecommunication lines and electrical interlocking lines were stretched and drainage structures restored.

[16] The reconstructed Khasan-Razdolnoye Road connecting Khasan, the ports of Zarubino and Posyet, and the settlement of Razdolnoye, Nadezhdinsky District was completed in November 2007.

Due to its sheltered and southerly location, it contains lesser seasonal swings than northerly inland areas.
