Nameks (ナメック星人, Namekku-seijin), also commonly known as Namekians, are a [race] from Planet Namek. They are among the most important races in the series, as they are the creators of the Dragon Balls. Nameks are humanoid with slug-like characteristics, including green skin and antennae. Namekians are fully grown at the age of eight (not counting demonic and Super Nameks). In the original Japanese versions of the King Piccolo / Piccolo Jr. Sagas of Dragon Ball, they were known as Mazokus, who had varying humanoid features and were of more earthly origin.

The name "Namek" is taken from the word namekuji, which means "slug" in Japanese.
