Fa'afafine are people who identify themselves as a third-gender in Samoa, American Samoa and the Samoan diaspora. A recognized gender identity/gender role since at least the early 20th century in Samoan society, and some theorize an integral part of traditional Samoan culture, fa'afafine are assigned male at birth, and explicitly embody both masculine and feminine gender traits, fashioned in a way unique to this part of the world. Their behavior typically ranges from extravagantly feminine to conventionally masculine.[1]

Traditionally, if a family had more boys than girls or not enough girls to help with women's duties about the house, male children would be chosen to be raised as fa'afafine.[2]

It has been estimated that 1-5% of Samoans identify as fa'afafine
