Melbourne Storm have won multiple NRL grand finals; their most recent premiership win was in the 2020 NRL Grand Final, played on 25 October 2020.

Key grand final wins

  • First premiership : Storm won their first NRL premiership in the 1999 grand final, coming back to beat St George Illawarra Dragons 20–18.
  • 2007 and 2009 note : Storm won the 2007 and 2009 grand finals on the field but were later stripped of those titles due to salary cap breaches, so they are not counted as official premierships.
  • 2012 premiership : Storm claimed an official premiership in the 2012 grand final, defeating the Canterbury-Bankstown Bulldogs 14–4.
  • 2017 premiership : They won again in 2017, defeating North Queensland Cowboys 34–6 in the grand final.
  • 2020 premiership (latest win) : Their latest grand final win came in 2020, when Melbourne Storm beat Penrith Panthers in the NRL grand final to secure what is recognised as their fourth official premiership.

Recent grand finals (no win)

  • 2025 NRL Grand Final : Storm reached the 2025 grand final but lost 26–22 to the Brisbane Broncos on 5 October 2025 at Accor Stadium in Sydney.
  • Commentary after that match described it as a dramatic comeback by Brisbane, overturning a 10‑point halftime deficit.
