The 1979 World Netball Championships was the fifth edition of the INF Netball World Cup, a quadrennial premier event in international netball.

It was held in Port of Spain, Trinidad and Tobago, featuring 19 teams.

[1] Australia, New Zealand and Trinidad and Tobago shared the title as there were no finals, instead the top 10 teams playing off in a round robin.

Each of the top three teams won eight out of nine matches, losing once, to one of the other two: New Zealand defeated Trinidad and Tobago 49–33; Trinidad and Tobago defeated Australia 40–38; and Australia defeated New Zealand 38–36.

The tournament rules of the time did not provide a way of determining an outright winner under the circumstances, so the three teams shared the title.
