The paramagnetic Meissner effect (PME) in the field cooled susceptibility hasbeen observed in superconducting single crystals of Ba_{1-x}K_xBiO_3 usingmagnetometers of Quantum-Design Co.. The PME is similar to that observed incuprates and Nb superconductors. For the Ba_{0.63}K_{0.37}BiO_3 crystal, thePME is observed in cooling process under the field up to 750 Oe. The PME wasnot found in the virgin-charged superconducting magnet. The PME is found in asuperconductor with trapped flux and may arise from a remnant field, atemperature inhomogeneity near T_c, and a potassium-concentrationinhomogeneity.Comment: 4 pages, 4 figure
