Porkkala Naval Base was a Soviet naval base operational from 1944–1956 in the municipalities of Kirkkonummi, Ingå and Siuntio on the Porkkala peninsula, 30 kilometers (19 mi) west of Helsinki, Finland.

The area was leased to the Soviet Union according to the Moscow Armistice signed in 1944 by Finland, the Soviet Union, and the United Kingdom. The area was returned to Finland in 1956. In the 21st century, it is the site of the Finnish naval base Upinniemi.
