Koninklijke Sint-Niklase Sportkring Excelsior was a Belgian football club from the town of Sint-Niklaas that merged with KSC Lokeren in 2000, establishing K.S.C.
The club then registered to the Belgian FA as Sint-Niklaassche S.K.
Right after World War II, Sint-Niklaassche qualified for the first division but only stayed at that level for two seasons.
Following the relegation, the name changed to Sint-Niklaasse S.K.
