Port of Zarubino, Commercial port in Trinity Bay, Russia

The Port of Zarubino is a sea port in Trinity Bay, northwestern Sea of Japan, in the settlement of Zarubino, southern Primorsky Krai. It lies 18 kilometres from the Chinese border and close to North Korea, and is ice-free year round. A railway from the port links north to Vladivostok, west to Hunchun in China's Jilin Province, and south to Rajin in North Korea via Khasan.

Construction of a fishing-industry seaport began in 1972, and in June 1973 the Primorrybprom order created the Directorate of the Trinity fishing port under construction. In July 1981 the enterprise Sea Fishing Port Trinity was formed at Zarubino, renamed Khasan Fishing Port in December 1988. In April 1992 the Khasan Sea Commercial Port of Trinity Bay was opened to foreign vessels.

The port's name comes from the village of Zarubino in Trinity Bay. Its rail line links Vladivostok with Hunchun in China's Jilin Province, where a high-speed rail terminus operates, and with Rajin in North Korea via Khasan. In May 2014 Jilin Province and the Summa Group signed a cooperation agreement at the CICA conference in Shanghai to develop the port.

The harbor remains navigable year-round without ice interference affecting operations. Visitors should contact local authorities to learn about access rules and whether guided tours of the facility are available.
