We have studied the influence of uniform and non-uniform distributed plasma on gravitational weak lensing around a black
hole in the presence of perfect fluid dark matter (PFDM). We have represented that the PFDM and plasma parameter has
opposite effect on the change of the value of the deflection angle of the light rays in a weak field regime.
