The strong decays of the heavy baryons \Sigma^{(*)}_Q \to \Lambda_Q \pi are studied by combining the chiral dynamics and the MIT bag model. In charm sector, we calculate the decay widths \Gamma(\Sigma^{(*)}_c\to \Lambda_c\pi) and compare with the experimental data and other theoretical estimations. In addition, we also predict the strong decay widths \Gamma(\Sigma^{(*)}_b\to \Lambda_b\pi).
