The city of Chorzów was formed in 1934–1939 by a merger of 4 adjacent cities: Chorzów, Królewska Huta, Nowe Hajduki and Hajduki Wielkie.
The name of the oldest settlement Chorzów was applied to the amalgamated city.

The etymology of the name is not known.
Chorzów is believed to be first mentioned as Zversov or Zuersov in a document of 1136 by Pope Innocent II as a village with peasants, silver miners, and two inns.
Another place-name likely indicating Chorzów is Coccham or Coccha, which is mentioned in a document of 1198 by the Patriarch of Jerusalem, who awarded this place to the Equestrian Order of the Holy Sepulchre of Jerusalem.
Chorzów is then mentioned as Chareu or Charev in 1257 and then Charzow in 1292.
The last name may originate from the personal name Charz, short for Zachary and may mean Zachary's place.
The a in the early names may have been later modified to the current pronunciation with o perhaps due to similarity to the common adjective chory=ill and a presence of a hospital (which was moved in 1299 to Rozbark at the gates of Bytom).
Today, the place of the old village is a subdivision called Chorzów III or Chorzów Stary = the Old Chorzów.

The industrial and residential settlement south-west of Chorzów constructed since 1797 around the Royal Coal Mine and Royal Iron Works was named Królewska Huta by the Poles or Königshütte by the Germans, both names meaning Royal Iron Works.
As it was growing quickly this settlement was granted city status in 1868.
Today this neighbourhood is called Chorzów I or Chorzów-Miasto meaning Chorzów Centre.

The etymology of Hajduki is ambiguous and is interpreted as either related to the German word for moorland (German: die Heide), or adopted from the German/Polish/Silesian term for hajduk(s) (Polish (plural): Hajduki; German (singular): Heiduck), which locally meant bandits.
The place was first mentioned in 1627 as Hejduk and shown on 18th century maps as "Ober Heiduk" and "Nieder Heiduk" (i.e., Upper and Lower Heiduk).
The later names Hajduki Wielkie and Nowe Hajduki mean Great Hajduks and New Hajduks, respectively.
The two settlements were merged in 1903 and named after the Bismarck Iron Works Bismarckhütte.
When the international borders shifted, the name of Bismarck was replaced with the name of the Polish king Batory (so-chosen to preserve that initial "B", which appeared on an economically important local trademark).
Today this city subdivision is called Chorzów IV or Chorzów-Batory.
