'Wallstreet' was an Allied unrealised initial plan for a direct assault by forces of Field Marshal Sir Bernard Montgomery’s Anglo-Canadian 21^st Army Group across the Nederrijn (Lower Rhine) river to take Arnhem and Appeldoorn in the German-occupied Netherlands (spring 1945).

The plan was later developed into 'Anger' (ii) for General H. D. G. Crerar’s Canadian 1^st Army.
