We present a catalog of 1543 candidate galaxy clusters found in the DR2 release of the Kilo-Degree Survey (KiDS), covering an area of 114 sq. degrees, in the redshift range 0<=z<=0.7. Based on simulated data, we derived a completeness ~85% and a purity of at least 80%. The catalog also includes the position and magnitude of the galaxy identified as the BCG; an estimate of the cluster masses, which were computed using the number of candidate cluster member galaxies as a proxy. Due to the limited area available in KiDS DR2, the calibration of the richness-mass relation is still preliminary, and will be improved in the next releases. (1 data file).
