SS Olza was the first dry cargo freighter built in Poland after the country regained independence - and the only large commercial ship built before World War II. Owned by Żegluga Polska company, she was named after the Olza River flowing through Cieszyn Silesia.

In 1918 Poland regained independence and a tiny strip of Baltic Sea coast. However, the traditional Polish port at Gdańsk was turned into a Free City of Danzig and so Poland had no port of her own - nor any shipyards. Thanks to the efforts of Eugeniusz Kwiatkowski the port of Gdynia was built, along with several shipyards serving both the Polish Navy and the merchant marine. Simultaneously, various Polish universities started to teach a cadre of future naval engineers. Among them was Henryk Giełdzik, a young engineer and a graduate of the Danzig university of technology.

The shipyards at Gdynia initially focused on smaller vessels, suitable for off-shore duty of Baltic Sea cruises, but not for the high seas. However, by the late 1930s the shipyards gathered enough experience and a decision was made to build a large dry cargo ship for the Polish merchant marine, the first such vessel built entirely at home. Designed by Henryk Giełdzik, the ship was named SS Olza, after an eponymous river flowing through Cieszyn Silesia.

The keel was laid August 28, 1938 in the Gdynia Shipyard. Most of the elements were produced by Świętochłowice-based Zgoda Steel Works, while minor parts were purchased from other contractors in Poland and the United Kingdom. The works continued as planned and launching was scheduled for mid-September 1939. However, on September 1, 1939 Germany invaded Poland starting the World War II. As the Polish-German border was only a dozen-or-so kilometres from Gdynia, the shipyard was almost on the front-line. Because of that, it was decided to launch the ship prematurely on September 8, 1939, in order to block the slipway in case the shipyard got under German control.

Following the German takeover of Gdynia, the ship was finished and drafted into the German marine. However, her eventual fate is unknown. She was not returned to Poland after the war and no trace of her has been found in German archives. Last of such investigations, intended to find the ship, were carried out in the 1980s by the Polish Television.
