|This article is about the Presidium in general. For the location in Mass Effect 3, see Presidium Commons.|
The Presidium is the gleaming heart of the Citadel. It is located in the 10km wide central ring of the station, home to the various government offices of the Citadel Council, as well as embassies for all of the species represented in the Citadel. While the Wards are home to most of the Citadel's population and are considered more lively, the Presidium is considered to be the province of Citadel space's most elite and powerful individuals.
The interior of the Presidium is landscaped to resemble a lush parkland on a 'G' type planet (using the Systems Alliance's Morgan-Keenan classification system). No detail was overlooked, boasting a large freshwater lake, verdant fields of grass, trees, and clouds, as well as artificial sunlight and gentle breezes. The Presidium goes through a brief day-night cycle, allowing six hours of darkness during which the 'sky' is darkened. The lakes on the Presidium act as reservoirs, independent from the water storage tanks in the wards. The water is purified to prevent bacteria from one species infecting another, due to the difference of amino acid structures that could prove fatal if ingested.
The buildings are built along the curving walls of the ring, and were meant to blend in unobtrusively with the surroundings. Located in the very heart of all this is the immense Citadel Tower, where the Citadel Council itself meets and holds audience with ambassadors from the various governments.

A male salarian and a human woman can be found chatting outside the Consort's Chambers on various topics. The woman mentions her office has been rearranged by the keepers five times this week. They also chat about entertainment on the Citadel, comparing the Embassy Bar to Chora's Den.
- The name Presidium is derived from the Latin praesidium, meaning fort, stronghold, or garrison.
- The Presidium's appearance is very similar to a 1976 artist's conception of the interior of a Stanford Torus space habitat.
