Nicknamed Les Dogues (The Mastiffs), Olympic Charleroi have played their home games at Stade de la Neuville, since 1920.

Olympic Club Caroloregian Lodelinsart was established on 20 September 1911 by 17-year-old Jules Ponsaert, and joined the Union Belge des Sociétés de Sports Athlétiques (Belgian Football Association; UBSSA) in 1912 and later registered with the Royal Belgian Football Association (RBFA) in June 1913.

The club gradually rose through the ranks, winning the third-division title in 1936 and earning promotion to the Belgian Second Division.

[2] Success came quickly; in 1937, under the presidency of Dr. Gaston Gianolla, Olympic won the second division title in the B series and achieved promotion to the top tier.

[2] Olympic's debut in the first division was marked by a strong showing, including a third-place finish after two seasons.

In 1947, Olympic recorded its best-ever league result, finishing as runners-up, just two points behind champions Anderlecht.

This drop was primarily caused by the ineligibility of player Jacques Leghait, leading to eight forfeited matches and a five-point penalty.

[7] The 2007–08 season began promisingly, but the club faltered and finished mid-table, narrowly avoiding relegation.

[15][16] The new club inherited Olympic's matricule and began competing in Belgium's highest amateur league, Belgian Division 1.
