Riga district (Latvian: Rīgas rajons) was an administrative division of Latvia, located in Semigallia and Vidzeme regions, in the centre of the country.

Across time localities of the Riga district had their resurgence and downturns caused by wars and unrest.

The reasons for the rapid development of Riga district can be found in its geographic position, human and natural resources, and rich heritage of culture and history.

[citation needed] The larger part of the former region lies in the sand-soil plains of Riga that are covered by pinewoods, low links, marshlands and level countryside that is typical for littoral lowlands.

The north-eastern part of former Riga district is covered by the largest deciduous forests in Latvia.
