what do most mexicans call mexico city?

Most Mexicans today most commonly call Mexico City “CDMX” in everyday speech, and more formally “Ciudad de México.”

Main names locals use

• CDMX
  • Widely used acronym you’ll see on signs, license plates, and in conversation.

* Became standard after the city’s official rebranding in 2016 to highlight its identity as its own federal entity rather than just the old “Distrito Federal.”

• Ciudad de México
  • The official full name, used in news, government, and more formal contexts.

* Many people still say it in full when they want to be clear they mean the city, not the country.

• D.F. / El DeFe (older usage)
  • Comes from “Distrito Federal,” the former official status of the city.

* Still heard among older speakers or nostalgically, but it’s less common with younger people since the 2016 change.

Other nicknames you might hear

These are not as universal as CDMX, but you’ll run into them:

• La capital – “the capital,” highlighting its role as the political and cultural center of Mexico.

• Chilangolandia – playful slang referencing “chilangos,” people from Mexico City. It’s more of an in-joke than a neutral name.

• La Ciudad de los Palacios – “the City of Palaces,” a historic, poetic nickname referring to its grand colonial architecture.

Simple rule of thumb

• If you want to sound natural and current: say CDMX.

• If you want to be formal: say Ciudad de México.

• If someone says D.F. or El DeFe , they’re using the older name that many still recognize.
