The magnetization and magnetic susceptibility of Bridgman-grown Sn_{1-x}Gd_{x}Te with values of x up to 0.09 have been measured over a temperature range from 2 to 300 K and in magnetic fields up to 5.5 T. The magnetic susceptibility data followed the Curie-Weiss relation with a small Curie temperature that indicated a weak antiferromagnetic coupling among Gd ions. The magnetic field dependence of the magnetization was fitted to a modified Brillouin function with parameter values that agreed fairly well with those from Curie-Weiss plots. The value of the exchange parameter was larger than in Pb_{1-x}Gd_{x}Te. The samples were p-type with carrier concentrations up to 1.3 x 10^{21} cm^{-3}. The ferromagnetic or spin-glass phase due to the RKKY interaction was not observed.
