Eufloria (formerly Dyson) is a real-time strategy video game developed by British studio Omni Systems Limited, consisting of independent developers Alex May, Rudolf Kremers and Brian Grainger.

Mac, Linux and Android versions of this game was pre-released along with Humble Indie Bundle for Android 4 on 8 November 2012.

It is set in a futuristic space environment, where the player assumes the role of the commander of interstellar lifeforms called Euflorians, who live and gain their resources on asteroids. The player has to use basic units that are grown on Dyson trees and are called "seedlings", to colonize and conquer asteroids. On asteroids, Dyson trees may be planted and as the tree grows and gets stronger, it will produce more seedlings with certain attributes. There are also flowers, defensive trees, and other units later in the game. Players battle other empires and seek to discover the origin of a mysterious grey menace, to speed up the return of the mythical Growers.

Eufloria has been described as a simple but charming game with calming music, graphics, and gameplay.
