The (Nörlund) logarithmic means of the Fourier series of the integrable function f is: 1/ln Σk=1n-1 Sk (f)/n -k, where ln:= Σk=1n-1 1/k. In this paper we discuss some convergence and divergence properties of this logarithmic means of the Walsh-Fourier series of functions in the uniform, and in the L1 Lebesgue norm. Among others, as an application of our divergence results we give a negative answer to a question of Moricz concerning the convergence of logarithmic means in norm.
