Abstract. The current algebra of classical nonlinear sigma models on arbitrary Riemannian
manifolds is analyzed. It is found that introducing, in addition to the Noether
current $j_\mu$ associated with the global symmetry of the theory, a composite
scalar field $j$, the algebra closes under Poisson brackets.
