The Torre Mayor is a skyscraper in Mexico City, Mexico. With a height of 225 meters (738 feet) to the top floor and 55 stories, it is the tallest building in Mexico and was, until 2010, the tallest building in Latin America, when it was surpassed by the 246-meter- (807-foot-) high Ocean Two in Panama City. Since then, multiple new buildings in Panama City have exceeded it in height and the Gran Torre Santiago in Santiago (Chile) (which is technically the tallest building in Latin America) has topped out at 300 meters (984 feet). In 2003 Torre Mayor surpassed by less than one meter the 225-meter- (738-foot-) high towers of the Parque Central Complex in Caracas (Venezuela). The Torre Mayor was developed by Canadian businessman Paul Reichmann, who also maintains part ownership. It is also part-owned by a group of institutional investors. The building was designed by the architectural firms of Zeidler Partnership Architects and Executive Architects Adamson Associates Architects, both of Toronto.

Located at Paseo de la Reforma, it was built by Canadian-owned Reichmann International on the former location of the Cine Chapultepec. Construction work began in 1999 and was finished in late 2003. Due to Mexico City's high propensity to earthquakes, the tower incorporates several anti-earthquake measures. With a height of 225 meters (740 feet) and 55 stories, the Torre Mayor is also one of the strongest buildings on Earth in terms earthquake resistance. The Torre Mayor building is designed to withstand earthquakes measuring 8.5 on the Richter Scale. In comparison, the U.S. Bank Tower can withstand an 8.3-intensity earthquake.
