The Lagrangian field theory have been generalized to accommodate the discussion of the Klein-Gordon and Dirac fields on noncommutative spacetime. The generalization of the Lagrangian field theory yields new definitions of Hamiltonian, momentum, and angular momentum of a field and the new definitions have been applied to the Klein-Gordon and Dirac fields on noncommutative spacetime.
