竞争性抑制剂(Competitive inhibitor)是一种酶抑制剂,竞争性抑制剂可能会和的活性部位结合,来和基质英语Substrate_(chemistry)(substrate)相互竞争,也可能是和基质结合,和酶相互竞争[1][2]

大部分竞争性抑制剂的功能是透过可逆的方式,和酶的活性部位结合[1]。因此许多资料来源会指出这是竞争性抑制剂的定义特征[3][4]。不过这可能是错误的简化,因为有许多可能的机制控制酶和抑制剂或是基质结合(不过无法同时和抑制剂及基质结合)[1]。例如变构抑制剂(allosteric inhibitor)可能会是竞争性抑制剂、非竞争性抑制剂英语non-competitive inhibition(non-competitive inhibition)或是反竞争抑制剂英语uncompetitive inhibition(uncompetitive inhibition)[1]
