History
Poland and Finland were once united by a personal union under the Polish–Swedish union during the reign of King Sigismund III Vasa.

In 1922, Poland and Finland were among signatories of the Warsaw Accord, which however did not enter into force, as Finland did not ratify it under pressure of Germany, which was hostile to Poland. Instead, in 1925, Poland and Finland together with Estonia and Latvia signed a convention on conciliation and arbitration in Helsinki.

In 1937–1938, both ethnic Poles and Finns in the Soviet Union were subjected to genocidal campaigns carried out by the NKVD, known as the Polish Operation and the Finnish Operation respectively. In 1939, both countries were victims of the German-Soviet Molotov–Ribbentrop Pact, according to which they were to be divided into "spheres of influence" between Nazi Germany and the Soviet Union. After the subsequent German-Soviet invasion of Poland at the start of World War II, Polish diplomats and consuls with families (apart from those arrested by the Soviets) were evacuated from the Soviet Union to Finland in October 1939. Later on, in November 1939, Finland became the second country to be invaded by the Soviet Union during World War II. As a result of World War II, both Finland and Poland lost their eastern territories to the Soviet Union, although Finland, unlike Poland, successfully retained independence while Poland fell under a quasi-colonial rule by the Soviet Union.

Modern relations

The Rail Baltica and Via Baltica, modern rail and road links of vital importance, connecting Finland with Poland and Central Europe, remain under construction (as of 2022).

Economic relations
The value of two-way trade between Poland and Finland in 2015 totaled EUR 2.8 billion.
