Hotel de México, Architectural structure in Mexico City, Mexico.

The Hotel de México was designed by Guillermo Rossell de la Lama as a 237-metre, 51-storey tower with 1,508 hexagonal rooms, intended to be the largest hotel in the Americas. Its unfinished concrete shell was later widened and clad in blue glass, and now houses the World Trade Center Mexico City.

Manuel Suárez y Suárez began the Gran Hotel de México in 1966, designed by Guillermo Rossell de la Lama to open for the 1968 Olympics with 1,508 hexagonal rooms in 51 stories. Financing problems and the peso crises of 1976 and 1982 stalled it; Suárez died in 1987 with the shell unfinished. Grupo Gusto converted it into the World Trade Center México, inaugurated on 19 November 1994.

The complex includes the Polyforum, a diamond-shaped building designed with David Alfaro Siqueiros to hold his mural; it opened before the painter died in 1974. Suárez and architect Guillermo Rossell de la Lama promoted the hotel through PRI rhetoric of "global communication and fraternity", and a 1971 exhibition with a scale model toured Paris, Madrid and New York.

The building stands on Avenida de los Insurgentes Sur at the corner of Filadelfia, on the site of the former Parque de Lama. The Polyforum Siqueiros, built as part of the same complex, is next door. The blue glass facade added in the 1990s hides the original concrete structure, so look for the building's bulk rather than the 1960s design.

The planned hotel was to include a heliport with customs facilities and a high-speed monorail to the Casino de la Selva in Cuernavaca. Its 1,508 rooms were hexagonal, and a panoramic elevator was designed to carry 100 tourists at once.
