We have succeeded to grow a single crystal of uranium ternary intermetallic compound UPdGa$$_5$$ by the Ga self-flux method. The magnetic susceptibility showed a weak temperature dependence and small anisotropy,consistent with an itinerant character of 5$$f$$ electrons. We observed a clear drop in the susceptibility and electrical resistivity below the Neel temperature $$T_N$$= 31 K. The magnetic structure was studied by means of a neutron diffraction measurement. We observed an antiferromagnetic peak with the propagation vector $$Q$$=[0,0,1/2]. The uranium 5$$f$$ moment of 0.33$$mu$$$$_{B}$$ parallel to the $$c$$-axis was found to order ferromagnetically in the basal $$c$$-plane and coupled antiferromagnetically along the $$c$$-axis.
