The 1979 World Netball Championships which was the fifth edition of the World Netball Championships tournament, the premier tournament in international netball, held once every four years. The 1979 tournament was held in Port of Spain, Trinidad and Tobago, with 19 teams competing.
Australia, New Zealand and Trinidad and Tobago were the joint winners of the 1979 Championships. The title was shared because there were no finals, 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 any other way of determining an outright winner, so the three teams shared the title.
