We find chaotic behavior for a particle with spin higher than some critical value (e.g. $S_{cr} \\sim 0.64 \\mu M$ for the total angular momentum $J=4 \\mu M$), where $\\mu$ and $M$ are the masses of a particle and of a black hole, respectively. The inverse of the Lyapunov exponent in the most chaotic case is about three orbital periods, which suggests that chaos of a spinning particle may become important in some relativistic astrophysical phenomena.
