K.V.C. Westerlo was founded in the city of Westerlo by students in 1917, and it was named Sportkring De Bist Westerlo. After five years of existence, the club retired. The club Bist Sport was created in 1931 and it changed its name to Sportkring Westerlo two years later. At that time. some players left the club to found Westerlo Sport, the ancestor of K.V.C. Westerlo. In 1939, the club won its league for the first time. Five years later, Sportkring Westerlo and dissident Westerlo Sport decided to merge in spite of the rivalry between the teams, and the new club was called V.C. Westerlo.
It became champion of the Antwerp second division in 1960. Eight years later it played its first season at the national level in Promotion and it won its league to play the third division in 1969. At the end of the season, Westerlo missed a third title in a row, finishing second behind Eupen. The next year, the club was relegated after the playoff and it stayed in the Promotion for ten seasons. The club then underwent two relegations in a row and thus played in the Antwerp second division in 1982–83. Westerlo was then promoted for three consecutive years to qualify for the third division once again. In 1993, the club promoted to the second division and then to the first division in 1997. In 1996, the club added the prefix Koninklijke (meaning "Royal" in Dutch) to its name.
On 18 June 2019 it was officially announced that the club was taken over by Turkish businessman Oktay Ercan. He immediately made it clear that KVC Westerlo will remain a regional family club, and that more attention will be paid to the social dimension and sporting ambitions. Ercan expressed his commitment in 2019 to a year-long plan called 'KVC Westerlo 2024'.[2]
