Construction of the stress tensor for a low differential order field theory on translation-invariant space is routine. If the underlying space is rotation, or Lorentz, invariant, an equivalent symmetric tensor can be found as well. Extension to nonlocal field equations, common, for example, in the statistical mechanical theory of fluids, is not routine and is carried out in this paper.
