Eyespace[1] is, informally, the space available for a group to make an eye or eyes. In practice, eye space consists of points on the board almost or entirely surrounded by a player. In tsumego problems, it is often important to reduce the eye space from the outside, for example by a hane. (See Futokoro.)

In the early stages of a game, a group's eye space is provided for by the group's base, giving eye potential. For eye spaces that are effectively surrounded by one colour, their quality depends on their eye shape.
