The 1996 American League Championship Series (ALCS), the second round of the 1996 American League playoffs, matched the East Division champion New York Yankees against the Wild Card team, the Baltimore Orioles. The Yankees had the home field advantage in the series because they had won their division and the Orioles were the Wild Card team.

The two teams were victorious in the AL Division Series (ALDS), with the Yankees defeating the West Division champion Texas Rangers three games to one, and the Orioles defeating the Central Division champion Cleveland Indians three games to one. The Orioles were the first wild card team to advance to the LCS. The Yankees won the series four games to one to become the American League champions, and won against the National League champion Atlanta Braves in the 1996 World Series.

New York won the series, 4–1.

The first game of the series is most notable for the infamous "Jeffrey Maier Incident." With the Yankees trailing 4–3 in the bottom of the eighth, rookie Derek Jeter hit a fly ball to deep right field off Orioles reliever Armando Benítez. Right fielder Tony Tarasco backed up to the wall, but twelve-year-old Yankees fan Jeffrey Maier reached over the fence and brought the ball into the stands and out of the field of play before Tarasco could attempt to catch the ball for a possible out. Tarasco immediately pointed above and protested that it was fan interference, but right field umpire Rich Garcia controversially ruled it a home run and his call was upheld by the other members of the umpiring crew. The game then went into extra-innings, where Bernie Williams ended it in the eleventh with a walk-off home run into the left field seats off Baltimore's Randy Myers.
