Klub Sportowy Czuwaj is a sports club from the Polish city of Przemyśl, founded by the scouting movement.

In 1947, with the arrival of communism in Poland, the club was under the patronage of the Polish State Railways.

This is when the club enjoyed its golden years, reaching an all-time high of 7th place in 1950 in the second division.

A different association reactivated the football team almost immediately under the name "Klub Sportowy Czuwaj".

The club has a fierce rivalry with neighbours Polonia Przemyśl and Zaglebie Sosnowiec.
