Gdynia-America Shipping Lines S.A. (Gdynia America Line - GAL) was a Polish-Danish joint stock company based in Gdynia, established in 1930 under the name of the Polish Transatlantic Shipping Company Limited (PTTO) in order to mark the Polish presence on the Atlantic; in 1934 transformed into Gdynia-America Shipping Lines.

In 1930 the Polish government, faced with growing emigration to North and South America, decided to purchase an existing shipping line (including ships and existing organizational apparatus) with the right to use piers in New York.

The Danish owners became eager to sell their interests, as in 1931 the United States authorities severely reduced immigrant quotas and the line was threatened with bankruptcy.

Ultimately, the claim was satisfied as part of the Polish-Danish compensation agreement signed on 26 February 1953.

Det Østasiatiske Kompagni A/S was granted a compensation in the amount of 1,220,000 Danish kronas (DKK).
