Rumia (Polish: [ˈrumja] ⓘ; Kashubian: Rëmiô; German: Rahmel) is a town in northern Poland, in the Wejherowo County in Pomeranian Voivodeship, with some 49,000 inhabitants.

The village of Rumia (then Rumina) was first mentioned in 1224 when it was awarded by Swietopelk II, later duke of Eastern Pomerania to the Cistercian convent in Oliwa (today part of Gdańsk).

[2] From 1320 to 1342 a Cistercian–Teutonic conflict took place, which ended with a privilege in which the Teutonic Knights confirmed the Cisterian possessions in the region, including Rumia.

579 of them were Germans and 180 were Kashubian or Polish,[7] while the present-day districts of Zagórze and Janowo had 754 and 161 inhabitants respectively, and remained predominantly Polish-Kashubian.

Labour migrants from other parts of Poland began to settle in the region including the village of Rumia and its vicinity.

By 1934, Rumia had become a suburb of Gdynia (population of 12,000 in 1939), located approximately 10 km (6 mi) from the city centre and well-connected with it through a railway link.

A small military airfield, home of two squadrons of the Coast Defence Escadrille (based in Puck) was opened to civilian planes on 1 May 1936.

During the German invasion of Poland in 1939, which started World War II, Rumia was a site of heavy fighting.

[11] Afterwards the town was occupied by Nazi Germany, which annexed it to the newly formed province of Reichsgau Danzig-West Prussia and renamed it to Rahmel.

Approximately half of the pre-war inhabitants of the town were expelled from 1939 to 1941, mostly to the General Government in the more eastern part of German-occupied Poland.

The Szybka Kolej Miejska (Urban Fast Train) makes two stops in the city, connecting it to Wejherowo, Gdynia, and beyond.
