We calculate the chiral corrections to the s-wave pseudoscalar meson
octet-baryon scattering lengths $a_{MB}$ to ${\cal O}(p^3)$ in the SU(3) heavy
baryon chiral perturbation theory (HB$\chi$PT). Hopefully the obtained
analytical expressions will be helpful in the chiral extrapolation of these
scattering lengths in the future lattice simulation.
