This paper is devoted to the investigation the fermion tunneling radiation of squashed black holes in the Gödel universe and charged Kaluza-Klein space-time. For black holes with different dimensions, establishing a set of appropriate matrices γ µ for the general covariant Dirac equation plays an important role in the semi-classical tunneling method. By constructing two sets of γ µ matrices, we have successfully derived the tunneling probability and Hawking temperature of the black holes.
