  We study the (2+1) dimensional Dirac equation in an homogeneous magnetic
field (relativistic Landau problem) within a minimal length, or generalized
uncertainty principle -GUP-, scenario. We derive exact solutions for a given
explicit representation of the GUP and provide expressions of the wave
functions in the momentum representation. We find that in the minimal length
case the degeneracy of the states is modified and that there are states that do
not exist in the ordinary quantum mechanics limit (\beta -->0). We also discuss
the mass-less case which may find application in describing the behavior of
charged fermions in new materials like Graphene.
