The New Zealand national women's rugby union team, called the Black Ferns, represents New Zealand in women's rugby union, which is regarded as the country's national sport. The team has won five of the past six Women's Rugby World Cups.

They have an 87% winning record in test match rugby, and are the only women's international side with a winning record against every opponent. Since their international debut in 1991, the Black Ferns have lost to only four of the 16 nations they have played in test matches.

The team's nickname combines the colour black and the silver fern, which are iconic New Zealand sporting symbols. For example, the All Blacks is New Zealand's famous men's rugby team, the Black Caps is the men's cricket team, the White Ferns is the women's cricket team, while the Silver Ferns is the national women's netball team.
