Body painting, or sometimes bodypainting, is a form of body art, considered by some as the most ancient form of art. Unlike tattoo and other forms of body art, body painting is temporary, painted onto the human skin, and lasts for only several hours, or at most (in the case of Mehndi or "henna tattoo") a couple of weeks. Body painting that is limited to the face is known as face painting.

Many artists work professionally as body painters across the world. Their work is seen regularly in television commercials, such as the Natrel Plus campaign featuring models camouflaged as trees. Body painters also work frequently in the film arena especially in science fiction with more and more elaborate alien creations being body painted. Stills advertising also used body painting with hundreds of body painting looks on the pages of the world's magazines every year.

The Sports Illustrated Swimsuit Issue, published annually, has in recent years featured a section of models that were body painted, attired in renditions of swimsuits or sports jerseys. Sometimes accessories are used such as bows or buttons. Some allege this allows SI to skirt their own no-nudity guideline.

There has been a revival of body painting in the Western society since the 1960s, in part prompted by the liberalization of social mores regarding nudity. Even today there is a constant debate about the legitimacy of body painting as an art form. The current modern revival could be said to date back to the 1933 World's Fair in Chicago where Max Factor and his model were arrested for causing a public disturbance when he bodypainted her with his new make-up formulated for Hollywood films.

Body art today evolves to the works more directed towards personal mythologies, as Jana Sterbak, Rebecca Horn, Youri Messen-Jaschin or Javier Perez.

Body painting is not always large pieces on fully nude bodies, but can involve smaller pieces on displayed areas of otherwise clothed bodies.

Body painting led to a minor alternative art movement in the 1950s and 1960s, which involved covering a model in paint and then having the model touch or roll on a canvas or other medium to transfer the paint. French artist Yves Klein is perhaps the most famous for this, with his series of paintings 'Anthropometries'. The effect produced by this technique creates an image-transfer from the model's body to the medium. This includes all the curves of the model's body (typically female) being reflected in the outline of the image. This technique was not necessarily monotone; multiple colors on different body parts sometimes produced interesting effects.

Joanne Gair is a leading body paint artist whose work appeared for the tenth consecutive year in the 2008 Sports Illustrated Swimsuit Issue. She burst into prominence with a August 1992 Vanity Fair Demi's Birthday Suit cover of Demi Moore.

Body painting is commonly used as a method of gaining attention in political protests, for instance those by PETA against Burberry.

Body painting with clay and other natural pigments existed in most, if not all, tribalist cultures. Often worn during ceremonies, it still survives in this ancient form among the indigenous people of Australia, New Zealand, the Pacific islands and parts of Africa. A semi-permanent form of body painting known as Mehndi, using dyes made of henna (hence also known rather erroneously as "henna tattoo"), was and is still practised in India and the Middle East, especially on brides. Since the late 1990s, Mehndi has become popular amongst young women in the Western world.

Indigenous peoples of South America traditionally use annatto, huito, or wet charcoal to decorate their faces and bodies. Huito is semi-permanent, and it generally takes weeks for this black dye to fade.

Actors and clowns around the world have painted their faces--and sometimes bodies--for centuries, and continue to do so today. More subdued form of face paints for everyday occasions evolve into the cosmetics we know today.
