Lattes is a commune in the Hérault département in the Occitainie region in southern France.

Lattes is located in the South of the prefecture of Montpellier in a plain split by the river Lez, that flows to the Mediterranean Sea at Palavas-les-Flots. Stretching from west to east, the hills announce the typical relief within the department.

The territory of the municipality is partially liable to flooding, when the level of the Lez rises. Areas near the river Lez and the Mosson river were protected by dykes. An environmental inspection report pointed the risk of three hundred dead in Lattes-Centre and other localities like les Marestelles and the necessity to provide accommodation. A spillway has been built in 2010.

The majority of the city's inhabitants live in the left bank where most of the business takes place. The Lattes-Centre and the Boirargues district are still separated by some farms, unused field and important commercial areas on the road going from Carnon to Montpellier.

In the south of Lattes, toward the coastline, the Pond of Mejean is the main site of the nature reserve where it is possible to appreciate bird watching. The natural house is the right place, at the entrance, to get some information about the Méjean ornithological park.
