The 2019 Oceania Rugby Women's Championship that was held in Fiji, was the 2021 Rugby World Cup qualifier for the Oceania region. The tournament was played at Churchill Park in Lautoka from 18 to 30 November 2019, with six teams entered. Australia and New Zealand sent development teams, having already qualified for the 2021 World Cup.

Format.
A split pool format was used for the Oceania tournament, with the teams seeded into two pools of three. Each team was scheduled to play one match against each of the teams in the opposite pool. However, following a measles outbreak in Tonga, the Tongan women's team had to withdraw from competition after one of their players arriving in Fiji was suspected of having measles. The tournament continued without playing their fixtures but a revised qualification process was put in place to allow Tonga to challenge later for the Oceania berth at the Rugby World Cup repechage qualifier.
The Black Ferns Development XV were undefeated in the tournament and won the 2019 Oceania Rugby Women's Championship  based on the combined pool standings, with Australia A as runner-up. Qualification to the World Cup remained up for grabs in Lautoka for the remaining three nations (excluding Australia and New Zealand). Fiji won direct entry to the World Cup by defeating Samoa in the qualifying playoff match.
Arrangements were made for a playoff match in early 2020 between Tonga and Papua New Guinea, with the winner to meet Samoa in another playoff match to decide the World Cup repechage berth.
