Toluca, officially Toluca de Lerdo , is the state capital of the State of Mexico as well as the seat of the Municipality of Toluca. With a population of 910,608 as of the 2020 census, Toluca is the fifth most populous city in Mexico. The city forms the core of the Greater Toluca metropolitan area, which with a combined population of 2,347,692 forms the fifth most populous metropolitan area in the country.
Located 63 km southwest of Mexico City, the city's rapid growth stems largely from its proximity to the capital.
When Toluca was founded by the Matlatzincas, its original name was Nepintahihui (land of corn). The current name is based on the Náhuatl name for the area when it was renamed by the Aztecs in 1473. The name has its origin in the word tollocan that comes from the name of the god, Tolo, plus the locative suffix, can, to denote "place of Tolo". It is also referred to in a number of Aztec codices as Tolutépetl, meaning hill of the god, Tolo, an allusion to the nearby volcano. The name Toluca de Lerdo was adopted in 1861 in honor of President Sebastián Lerdo de Tejada.
