In this paper, the microcausality of quantum field theory on spin-induced noncommutative spacetime is discussed. It is found that for space-like separation the microcausality is not obeyed by the theory generally. It means that Lorentz covariance cannot guarantee microcausality in quantum field theory. We also give some comments about quantum field theories on such noncommutative spacetime and the relations between noncommutative spacetime and causality.
