Sticker art (Sometimes called sticker bombing or slap tagging) is a form of street art in which the message is conveyed by stickers. Sticker art is most noticeable in well-trafficked urban areas. Stickers may promote a political agenda (such as the anti-war and anti-George W. Bush stickers below), comment on a policy or issue (such as the MIT sticker below), or comprise an avantgarde art campaign (see This Is A Heavy Product and Obey Giant). pop.ac (formerly known as Art Collart), a Hamburg artist, works since 1987 with sticker.

Sticker art is popular with teenagers, due mostly to ready availability of supplies. Sometimes, unintentional sticker art can occur, with unconventional discards of free stickers, for example free stickers from voting booths, retail stickers, United States Postal Service labels, and stickers acquired from school drug-awareness programs. Free blank or mostly blank stickers can create intentional sticker art, artists can draw, paint, stencil or write whatever they want on their stickers. Popular blank stickers are USPS and DHL lables and 'hello my name is' name tags.
