Which team did Tom Brady defeat in his last AFC Championship game?

Tom Brady defeated the Kansas City Chiefs in his last AFC Championship game. The New England Patriots beat Kansas City 37–31 in overtime at Arrowhead Stadium on January 20, 2019, in the AFC Championship for the 2018 NFL season.

The game was a dramatic meeting between Brady and Chiefs quarterback Patrick Mahomes, who was making his first AFC Championship appearance. New England built an early lead, but Kansas City repeatedly answered, sending the game into overtime after a frantic fourth quarter in which the teams combined for 38 points. Brady directed the Patriots’ opening overtime possession, and Rex Burkhead finished it with a two-yard touchdown run.

The victory sent New England to Super Bowl LIII, where the Patriots defeated the Los Angeles Rams 13–3. It was Brady’s ninth AFC Championship win and his final conference title with New England. The Chiefs later defeated the Patriots 23–16 in the 2019 regular season, but that was not an AFC Championship game, which is why the Chiefs remain the correct answer to this question.
