FK ČSK Čelarevo (Serbian Cyrillic: ФК ЧСК Челарево) is a football club from Čelarevo, a village near Bačka Palanka, Serbia. It was founded in 1925 as ČOSK (Serbian: Čebski Omladinski Sportski Klub or ЧОСК, Чебски Омладински Спортски Клуб). The village of Čelarevo was called Čeb before World War II, hence the name.
The club was formed in 1925. In 1946, the club changed its name to Radnički Čelarevo until 1950 when the club was called SK Podunavlje. By the end of the year, the club had entered to the Championship of Novi Sad. They played there for two years. In 1952 they played in the Regional League of Novi Sad. In 1953 Podunavlje and another football club called Krajišnik joined and formed ČSK. From 1964 to 1967, the club played in First League of Vojvodina (4th tier). They again entered the league in 1969 and stayed there for three more seasons. For seventeen years they played in lower regional leagues but in 1989 they returned to the First League of Vojvodina. They stayed there for only one season but they got back after only one season in lower league. In 1993 club entered the Serbian League North (3rd tier). It managed to enter the Second League of FR Yugoslavia in 1998 and stayed there for four years. From 2002 to 2005 they played in Serbian League Vojvodina (which was before called North).
