We investigate the asymptotic supersymmetry group of the near horizon region of the BMPV black holes, which are the rotating BPS black holes in five dimensions. When considering only bosonic fluctuations, we find that there exist consistent boundary conditions and the corresponding asymptotic symmetry group is generated by a chiral Virasoro algebra with the vanishing central charge. After turning on fermionic fluctuations with the boundary conditions, we construct the conserved charges associated with the infinitesimal asymptotic Killing spinors. The conserved charges satisfy a chiral super-Virasoro algebra without central extension. The super-Virasoro algebra is originated in the AdS2 isometry supergroup of the near horizon solution.
