Torre Reforma Colón, Office building in Reforma Avenue, Mexico

Torre Reforma Colón is a cancelled skyscraper project on Avenida Reforma in Mexico City, designed by Javier Sordo Madaleno for Grupo Kaluz. Planned at 316 metres and 72 floors, it was to be the city's tallest building. Construction began in 2019 but halted after early concrete and steel work, and the project was cancelled in 2026.

Torre Reforma Colón was presented on 11 March 2015 and approved for construction in 2016; work on its first concrete and steel elements began in 2019 but soon stalled with little progress. The 316-metre, 72-floor tower, designed by Javier Sordo Madaleno for developer Grupo Kaluz at an estimated cost of 2 billion dollars, was to be Mexico City's tallest; its cancellation was announced in 2026. It replaced the Torre Santander project, presented in 2010 and cancelled in 2012, which had in turn displaced buildings such as Reforma 76 (Mario Pani, 1954) and Morelos 110 (Augusto H. Álvarez and Juan Sordo Madaleno, 1948).

The project was to replace the Torre Santander, presented in October 2010 and cancelled in 2012, which in turn displaced buildings such as Reforma 76 (Mario Pani, 1954), Morelos 110 (Augusto H. Álvarez and Juan Sordo Madaleno, 1948) and Morelos 104. The complex was to include four other towers for offices, a hotel and housing, linked by a large commercial component; one was planned on the site of the former Cine París.

The site is a stalled construction plot on Avenida Reforma, where only the first concrete and steel elements went up from 2019 before work stopped; there is no finished tower to enter. The wider complex was planned around the Cine París lot, the Fiesta Americana hotel site, the Atenas–Versalles corner and the block bounded by Abraham González, Atenas and Bucarelli, linked by an elevated passage.
