Provided is an antifouling coating composition having excellent long-term storage stability, as well as an antifouling coating composition for forming a highly environmentally safe antifouling coating film which can maintain consistent coating film solubility and antifouling capability, and which does not give rise to coating film defects such as cracks,when exposed to seawater for an extended period. According to the present invention,there is provided an antifouling coating composition containing: (A) a triorganosilyl ester-containing copolymer obtained from a mixture of (a) a meth(acrylic) acid triorganosilyl ester monomer represented by general formula (1):(in the formula, R1 denotes a hydrogen atom or the methyl group;R2, R3, and R4 may be the same or different, and each denote C3-6,aphla-position branched alkyl groups or phenyl groups) and (b) an ethylenically unsaturated monomer copolymerizable with the meth(acrylic) acid triorganosilyl ester monomer;and (B) a hydrate of calcium sulfate.
