The Macroplaza or La Gran Plaza is a town square or plaza located in the heart of the city of Monterrey, Mexico.

The Macroplaza was built in the early 1980s during the governorship of Alfonso Martínez Domínguez. The construction of the Macroplaza required the demolition of several old buildings and houses including a famous movie theater.

The Macroplaza is presently the second largest plaza in the world. It has an extension of 400,000 square metres consisting of various monuments, smaller plazas and gardens.

One of the most iconic monuments of the city is the Faro del Comercio (Lighthouse of Commerce), a 70 meters tall modern lighthouse located in the same plaza, equipped with a green laser, that shot its light around the city at nights.
