The 2019 Netball Quad Series was the seventh Netball Quad Series series. It was hosted by England Netball. It featured Australia, England, New Zealand and South Africa playing each other in a series of six netball test matches in January 2019. The first two matches were played at Liverpool's M&S Bank Arena while the remaining four were played at London's Copper Box Arena.
With a team coached by Lisa Alexander and captained by Gabi Simpson and Caitlin Thwaites, Australia won the series over England on goal difference, having defeated both South Africa and New Zealand. Despite wins over New Zealand and Australia, a loss to South Africa ultimately cost England their first Netball Quad Series title. The series was broadcast live on Nine/9Gem in Australia and on Sky Sports in the United Kingdom and Ireland.
