We succeeded in growing a high-quality single crystal of an antiferromagnet UNiGa5 by the self-flux method, and measured the de Haas-van Alphen (dHvA) effect, together with the electrical resistivity, magnetoresistance, magnetic susceptibility and specific heat. Reflecting the peculiar tetragonal structure, the Fermi surface consists of one cylindrical and two closed ellipsoidal surfaces. The cyclotron mass is not large, ranging from 1.3 to 3.1m0.
