The Grid is a vast part of the Tron system, programmed by Kevin Flynn. Often referred to by Flynn as his "digital frontier", the Grid was made to provide an experimental platform where all forms of research could be carried out at unparalleled speeds. Perceived time on the Grid is measured in cycles and run at a pace far greater than time perceived in the real world, thus allowing anyone immersed in the computer environment to perform the same functions in a fraction of the time it would take them otherwise.

Much of the Grid consists of a flat, dark platform with glowing blue, cyan, or white ribbons of light covering it in a vast latticework. Within the Grid itself lie a number of cities, the most populous being Tron City, a metropolis modeled on a real world city which hosts a diverse range of programs. The programs carry out all the day-to-day tasks involved in running the system. On the periphery of the Grid lies the Outlands, an inhospitable region where most programs never venture.

In TRON: Uprising, other known cities on the Grid include far-off Argon City and its neighbor Purgos. Concept art for a location used in one episode was labeled with the name "Gallium City," but the name never appeared in the show.
