In this note we prove that the maximum principle of Jäger-Kaul for harmonic maps holds for a more general class of maps, V -harmonic maps. This includes Hermitian harmonic maps [?], Weyl harmonic maps [?], affine harmonic maps [?] and Finsler maps from a Finsler manifold into a Riemannian manifold. With this maximum principle we establish the existence of V -harmonic maps into regular balls.
