The teeing ground is the area where play begins in a hole of golf. The terms tee, tee box, and "teeing ground" are synonymous. The name derives from the tee used to elevate a golf ball before striking it to commence play.

The boundaries of the teeing ground are defined by a pair of tee markers. The front, left and right sides of the tee are denoted by the outer edges of the tee markers, assuming the perspective of a player standing in the teeing ground and facing the hole. The teeing ground is two club-lengths in depth.

​

Most courses have at least three sets of tee markers (some may have six or more), each a different color and denoting different yardages. Some tee marker colors commonly used in the United States are below, along with a general description of who plays from what color. The tee box that a person plays from is not set by rules; in casual play, anyone can use any tee box they wish to. Note that not all courses have all colors, and some may use a completely different color scheme for their tee markers.
