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.
[1] 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.
[2] Buckley and Goodes polled three votes in matches only twice during the season – the least by any Brownlow Medal winner.
The votes are kept secret until the awards night, and they are read and tallied on the evening.
[4] As the medal is awarded to the fairest and best player in the league, those who have been suspended during the season by the AFL Tribunal (or, who avoided suspension only because of a discount for a good record or an early guilty plea) are ineligible to win the award; however, they may still continue to poll votes.
