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 on.) tatau. In Marquesan, tatu." Prior to 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 physique modification term is not to be confused with the origins of the word for the military drumbeat or functionality — 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 and every 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 first voyage to Tahiti and New Zealand. In his narrative of the voyage, he refers to an operation known as "tattaw".

Tattoo enthusiasts might refer to tattoos as "ink", "pieces", "skin art", "tattoo art", "tats" or "work"; to the creators as "tattoo artists", "tattooers" or "tattooists"; and to locations where they operate as "tattoo shops", "tattoo studios" or "tattoo parlors".Mainstream art galleries hold exhibitions of both conventional and custom tattoo designs, such as Beyond Skin, at the Museum of Croydon. Copyrighted tattoo styles that are mass-made and sent to tattoo artists are identified as "flash", a notable instance of industrial design and style.[8] Flash sheets are prominently displayed in several tattoo parlors for the purpose of delivering both inspiration and prepared-produced tattoo pictures to consumers.

The Japanese word irezumi implies "insertion of ink" and can mean tattoos employing tebori, the traditional Japanese hand technique, a Western-style machine or any approach of tattooing employing insertion of ink. The most common word utilised for conventional Japanese tattoo designs is horimono. Japanese could use the word tattoo to imply non-Japanese designs of tattooing.
