  A Lagrangian formulation is given extending to N = 1 supersymmetry the motion
of a charged point particle with spin in a non-abelian external field. The
classical formulation is constructed for any external static non-abelian SU(N)
gauge potential. As an illustration, a specific gauge is fixed enabling
canonical quantization and the study of the supersymmetric non-abelian Landau
problem. The spectrum of the quantum Hamiltonian operator follows in accordance
with the supersymmetric structure.
