At the end of World War II, Chorzów (with the balance of Silesia) was re-incorporated into Poland.
Generally, the Chorzów industry suffered little damage during World War II due to its inaccessibility to Allied bombing, a Soviet Army enveloping manoeuvre in January 1945, and perhaps Albert Speer's slowness or refusal to implement the scorched earth policy.
This intact industry now played a critical role in the post-war reconstruction and industrialization of Poland.
After the war, businesses were nationalized and operated, with minor changes, till 1989.
Some were used as Soviet labour and concentration camps.
Some industrial hardware and at least 100 000 Polish Silesians were deported to the Ukrainian Donbass region.
At the "fall of communism" in 1989, the area was in decline.
Since 1989, the region has been transitioning from heavy industry to a more diverse economy.

On 28 January 2006, a roof collapsed at an exhibition hall, killing 65 people.
See Trade hall roof collapse in Katowice, Poland.

In 2007, Chorzów became a part of Upper Silesian Metropolitan Union, a voluntary union of a continuous chain of cities aimed at increasing the poor visibility of the area, improving its competitiveness, and modernizing the infrastructure.

The region experienced several waves of migrations, including those commencing in 1945 (to Germany and from Poland and Ukraine), in 1971–1976 (to Germany), in 1982 (to Western countries), and from 2003 (to other countries of the EU).
