Noisy-le-Grand (French pronunciation: [nwazi lə ɡʁɑ̃] ⓘ) is a commune in the eastern suburbs of Paris, France.

Some of the postmodern architecture in the commune has been used as a shooting location in movies including Brazil and The Hunger Games.

The epithet "le-Grand" (Medieval Latin: Magnum), meaning "the Great", was added in the Middle Ages, probably to distinguish Noisy-le-Grand from the smaller settlement of Noisy-le-Sec, which was sometimes referred to as Nucenum Minus ("Noisy the Small").

The city also includes significant, but less numerous, communities from Portugal and North African countries like Morocco and Algeria.

Previously Star Airlines (now XL Airways France) had its headquarters in the Immeuble Horizon building in the commune.
