Alexis Nihon Complex (French: Complexe Alexis Nihon) is a 223,000 m2 (2,400,000 sq ft) building complex in Downtown Montreal, Quebec, Canada (on the border with Westmount), consisting of a shopping centre, two office towers, and a residential building. It is named after the inventor and businessman Alexis Nihon. The shopping mall is directly connected to the Atwater metro station, which joins the building by a short tunnel with the adjacent Dawson College, and by a longer one adjoins nearby Westmount Square. The original complex was designed by the Montreal architect Harold Ship, and its architectural plans are housed at the Canadian Centre for Architecture.
