An allotment (British English), or in North America, a community garden, is a plot of land made available for individual, non-commercial gardening or growing food plants, so forming a kitchen garden away from the residence of the user. Such plots are formed by subdividing a piece of land into a few or up to several hundred parcels that are assigned to individuals or families. Such parcels are cultivated individually, contrary to other community garden types where the entire area is tended collectively by a group of people. In countries that do not use the term "allotment (garden)", a "community garden" may refer to individual small garden plots as well as to a single, large piece of land gardened collectively by a group of people. The term "victory garden" is also still sometimes used, especially when a community garden dates back to the First or Second World War.

The individual size of a parcel typically suits the needs of a family, and often the plots include a shed for tools and shelter, and sometimes a hut for seasonal or weekend accommodation. The individual gardeners are usually organised in an allotment association, which leases or is granted the land from an owner who may be a public, private or ecclesiastical entity, and who usually stipulates that it be only used for gardening (i.e., growing vegetables, fruits and flowers), but not for permanent residential purposes (this is usually also required by zoning laws). The gardeners have to pay a small membership fee to the association, and have to abide by the corresponding constitution and by-laws. However, the membership entitles them to certain democratic rights.
