Abstract：
The spectral function of rho meson in hot and dense pion medium is studied within an effective model which describes the ρ-π coupling. The results from numerical calculation show that the spectral function becomes wider and the position of the peak moves towards the high invariant mass region when the temperature and the pion chemical potential increase.
