An artifact, [a] or artefact (see American and British English spelling differences), is something made or given shape by humans, such as a tool or a work of art, especially an object of archaeological interest. 
In archaeology, however, the word has become a term of particular nuance and is defined as: an object recovered by archaeological endeavor, which may be a cultural artifact having cultural interest. However, modern archaeologists take care to distinguish material culture from ethnicity, which is often more complex, as expressed by Carol Kramer in the dictum "pots are not people". 
Examples include stone tools, pottery vessels, metal objects such as weapons, and items of personal adornment such as buttons, jewelry and clothing. Bones that show signs of human modification are also examples. Natural objects, such as fire cracked rocks from a hearth or plant material used for food, are classified by archeologists as ecofacts rather than as artifacts.
Artifacts can come from any archaeological context or source such as:
- Buried along with a body
- From any feature such as a midden or other domestic setting
- Votive offerings
- Hoards, such as at wells
Artifacts are distinguished from the main body of the archaeological record such as stratigraphic features, which are non-portable remains of human activity, such as hearths, roads, deposits, trenches or similar remains, and from biofacts or ecofacts, which are objects of archaeological interest made by other organisms, such as seeds or animal bone.
Natural objects that humans have moved but not changed are called manuports. Examples include seashells moved inland, or rounded pebbles placed away from the water action that made them.
These distinctions are often blurred. For instance, a bone removed from an animal carcass is a biofact, but a bone carved into a useful implement is an artifact. Similarly there can be debate over early stone objects that could be either crude artifacts or naturally occurring and happen to resemble early objects made by early humans or Homo sapiens. It can be difficult to distinguish the differences between actual man-made lithic artifacts and geofacts – naturally occurring lithics that resemble man-made tools. It is possible to authenticate artifacts by examining the general characteristics attributed to man-made tools and local characteristics of the site. 
In ethnography and archaeology, a category of "ancestral artifact" has been proposed, defined as "any object of natural raw material (chert, obsidian, wood, bone, native copper, and so on) made by a people following a lifestyle based on foraging (e.g. hunting, gathering) and/or basic agriculture or pastoralism (e.g. horticulture, transhumance)".
