We study gravitational lensing by a black hole in the framework of the poincaré gauge theory of gravity. By using a recent black hole solution in this setup, we derive the deflection angle for light rays grazing the black hole and numerically solve the resulting integral. Numerical result show that the effects of torsion generally increases the deflection angle.
