The magnetic susceptibility of Bridgman-grown Sn_{1-x}Eu_{x}Te with nominal values of x up to 0.095 was measured over a temperature range from 2 to 385 K. The samples were p-type with hole concentrations up to 1.5 × 10^{21} cm^{-3}. The susceptibility data above 50 K followed the Curie-Weiss relation with a small Curie temperature. At about 10 K a small cusp in susceptibility was observed in samples with the higher range of x values. The data indicate a presence of both antiferromagnetic and ferromagnetic exchange interactions, with some paramagnetic contributions from charged defects. There is also evidence of Eu going into the lattice both as Eu^{2+} and Eu^{3+} ions.
