Liinakhamari (Russian: Лиинахамари; Finnish: Liinahamari; Swedish: Linhammar) is an ice-free harbour and a rural locality in Pechengsky District of Murmansk Oblast, Russia.

During the Russo-Finnish Winter War, the Soviet Union conquered Liinakhamari, but it was returned to Finland in the Moscow Peace Treaty.

10,000 men worked along the Arctic Sea Road helping thousands of trucks to transport cargo from the northernmost railway station in Rovaniemi to Liinakhamari harbour.

The trip was almost 1,100 kilometres (700 mi) north along the narrow gravelled road, in the middle of sparsely inhabited Arctic taiga.

During the Cold War, the harbour was a submarine base, and at present it houses border patrol boats.
