The 2003 Brownlow Medal was the 76th year the award was presented to the player adjudged the fairest and best player during the Australian Football League (AFL) home-and-away season. Nathan Buckley of the Collingwood Football Club, Adam Goodes of the Sydney Swans, and Mark Ricciuto of the Adelaide Football Club all won the medal by polling twenty-two votes each during the 2003 AFL season. Buckley and Goodes polled three votes in matches only twice during the season – the least by any Brownlow Medal winner.
