We study Chern-Simons black holes in d-dimensions and we calculateanalytically the quasinormal modes of fermionic perturbations. Also, weconsider as background the five-dimensional Chern-Simons black hole withtorsion and the BTZ black hole with torsion. We have found that the quasinormalmodes depend on the highest power of curvature present in the Chern-Simonstheory, such as occurs for the quasinormal modes of scalar perturbations. Wealso show that the effect of the torsion is to modify the real part of thequasinormal frequencies, which modify the oscillation frequency of the fieldfor the five dimensional case. However, for the BTZ black hole with torsion,the effect is to modify the imaginary part of these frequencies, that is, therelaxation time for the decay of the black hole perturbation. The imaginarypart of the quasinormal frequencies is negative which guaranties the stabilityof these black holes under fermionic field perturbations.
