Mérida has been nicknamed "The White City" (La Ciudad Blanca), though the exact origin of this moniker is not clear. Some explanations include the common color of its old buildings painted and decorated with "cal" or the fact that the residents keep the city particularly clean. Mérida was named after the Spanish town of the same name, originally (in Latin) Augústa Emérita (see Mérida, Spain). Mérida has served as the American Capital of Culture in the years 2000 and 2017.

Mérida is located in the northwest part of the state of Yucatán, which occupies the northern portion of the Yucatán Peninsula. To the east is the state of Quintana Roo, to the west is the state of Campeche, to the north is the Gulf of Mexico, and far to the south is the state of Chiapas. The city is also located in the Chicxulub Crater. It has a very flat topography and is only 30 feet (9 m) above sea level. The land outside of Mérida is covered with smaller scrub trees and former henequen fields. Almost no surface water exists, but several cenotes (underground springs and rivers) are found across the state. Mérida has a centro histórico typical of colonial Spanish cities. The street grid is based on odd-numbered streets running east/west and even-numbered streets running north/south, with Calles 60 and 61 bounding the "Plaza Grande" in the heart of the city. The more affluent neighborhoods are located to the north and the most densely populated areas are to the south. The Centro Histórico area is becoming increasingly popular with Americans and other expatriates who are rescuing and restoring the classic colonial structures. In 2007 the Los Angeles Times recently noted this surge of interest in rescuing Mérida's historic downtown.
