The word tattoo, or tattow in the 18th century, is a loanword from the Samoan word tatau, which means "to strike". The Oxford English Dictionary gives the etymology of tattoo as "In 18th c. tattaow, tattow. From Polynesian (Samoan, Tahitian, Tongan, and so forth.) tatau. In Marquesan, tatu." Just before the importation of the Polynesian word, the practice of tattooing had been described in the West as painting, scarring or staining.The etymology of the body modification term is not to be confused with the origins of the word for the military drumbeat or performance — see military tattoo. In this case, the English word tattoo is derived from the Dutch word taptoe.The very first written reference to the word tattoo (or tatau) seems in the journal of Joseph Banks (24 February 1743 – 19 June 1820), the naturalist aboard explorer James Cook's ship HMS Endeavour: "I shall now mention the way they mark themselves indelibly, each of them is so marked by their humour or disposition".[5] The word tattoo was brought to Europe by Cook, when he returned in 1769 from his very first voyage to Tahiti and New Zealand. In his narrative of the voyage, he refers to an operation known as "tattaw".

Tattoo enthusiasts may refer to tattoos as "ink", "pieces", "skin art", "tattoo art", "tats" or "work"; to the creators as "tattoo artists", "tattooers" or "tattooists"; and to areas exactly where they function as "tattoo shops", "tattoo studios" or "tattoo parlors".Mainstream art galleries hold exhibitions of both traditional and custom tattoo styles, such as Beyond Skin, at the Museum of Croydon. Copyrighted tattoo designs that are mass-created and sent to tattoo artists are identified as "flash", a notable instance of industrial style.[8] Flash sheets are prominently displayed in many tattoo parlors for the purpose of offering each inspiration and ready-made tattoo images to buyers.

The Japanese word irezumi indicates "insertion of ink" and can imply tattoos employing tebori, the conventional Japanese hand technique, a Western-style machine or any technique of tattooing utilizing insertion of ink. The most widespread word utilized for traditional Japanese tattoo styles is horimono. Japanese might use the word tattoo to mean non-Japanese designs of tattooing.
