The magnetotransport properties of cubic ${\\rm Sr_{3}PbO}$ antiperovskite, theoretically proposed to be a 3D massive Dirac electron system, are studied. The measurements of Shubnikov-de Haas oscillations and Hall resistivity indicate the presence of a low density ($\\sim 1 \\times 10^{18}$ ${\\rm cm^{-3}}$) of holes with an extremely small cyclotron mass of 0.01-0.06$m_{e}$. The magnetoresistance $\\Delta\\rho_{xx}(B)$ is linear in magnetic field $B$ with the magnitude independent of temperature.
