A multidimensional cosmological model with space-time consisting of n (n > 2) Einstein spaces M_i is investigated in the presence of a cosmological constant Λ and a homogeneous minimally coupled scalar field φ(t) as a matter source. Classical and quantum wormhole solutions are obtained for Λ < 0 and all M_i being Ricci-flat. Classical wormhole solutions are also found for Λ < 0 and only one of the M_i being Ricci-flat for the case of spontaneous compactification of the internal dimensions with
