A lawn game is any outdoor game that can be played on a lawn. Many games that are traditionally played on a pitch are marketed as "lawn games" for home use in a front or back yard.

Common lawn games include:

A lawn is an area of aesthetic and recreational land planted with grasses or other durable plants and can be defined by four characteristics: It is composed only of grass species; it is subject to weed and pest control; it is subject to practices aimed at maintaining its green color; and it is regularly mowed to ensure an acceptable length . Low ornamental meadows in natural landscaping styles are a contemporary option of a lawn. In recreational contexts, the specialised names turf, pitch, field or green may be used, depending on the sport and the continent.

The term lawn, referring to a managed grass space, dates to no earlier than the 16th century. Tied to suburban expansion and the creation of the household aesthetic, the lawn is an important aspect of the interaction between the natural environment and the constructed urban and suburban space.

Lawns are a common feature of private gardens, public landscapes and parks in many parts of the world. They are created for aesthetic pleasure, as well as for sports or other outdoor recreational use. Lawns are useful as a playing surface both because they mitigate erosion and dust generated by intensive foot traffic and because they provide a cushion for players in sports such as rugby, football, soccer, cricket, baseball, golf, tennis, hockey and lawn bocce.

A game is structured playing, usually undertaken for enjoyment and sometimes used as an educational tool. Games are distinct from work, which is usually carried out for remuneration, and from art, which is more often an expression of aesthetic or ideological elements. However, the distinction is not clear-cut, and many games are also considered to be work (such as professional players of spectator sports/games) or art (such as jigsaw puzzles or games involving an artistic layout such as Mahjong, solitaire, or some video games).

Key components of games are goals, rules, challenge, and interaction. Games generally involve mental or physical stimulation, and often both. Many games help develop practical skills, serve as a form of exercise, or otherwise perform an educational, simulational, or psychological role.

Attested as early as 2600 BC, games are a universal part of human experience and present in all cultures. The Royal Game of Ur, Senet, and Mancala are some of the oldest known games.
