The 2023 Brownlow Medal was the 96th year the award was presented to the player adjudged the best and fairest player during the Australian Football League (AFL) home-and-away season. It was won by Lachie Neale for the second time, with 31 votes; Neale had previously won the medal in 2020. The count took place on Monday 25 September, five days before the grand final. Neale had been only fifth favourite in Brownlow Medal betting markets prior to the count, and his victory was considered a surprise.
The four field umpires (those umpires who control the flow of the game, as opposed to goal or boundary umpires) confer after each match and award three votes, two votes, and one vote to the players they regard as the best, second-best and third-best in the match, respectively. The votes are kept secret until the awards night, and they are read and tallied on the evening.
