Abstract. New Wiener amalgam spaces are introduced for local Hardy spaces. It is proved that the maximal Fejér operator is bounded from the amalgam space $W(h_{p},\ell_\infty )$ to $W(L_{p},\ell_\infty )$. This implies the almost everywhere convergence of the Fejér means for all $f\in W(L_{1},\ell_\infty )\supset L_1$.
