The 2017 American League Division Series were two best-of-five-games series held in Major League Baseball’s (MLB) 2017 postseason to determine the participating teams in the 2017 American League Championship Series. The three divisional winners (seeded 1–3) and a fourth team—the winner of a one-game Wild Card playoff—played in two series.

These matchups were:

For the first time, Major League Baseball sold presenting sponsorships to all of its postseason series; Doosan acquired presenting sponsorship to the ALDS, and thus the series was officially known as the American League Division Series presented by Doosan.

The Astros would go on to defeat the Yankees in the ALCS, then win the 2017 World Series over the National League champion Los Angeles Dodgers. It was the Astros first-ever MLB title.

New York won the series, 3–2.

Houston won the series, 3–1.

This was the fourth postseason meeting between the Indians and Yankees, with Cleveland winning two of the three previous series including both times in the ALDS (1997 and 2007). The Yankees won the 1998 ALCS.

Cy Young Award candidate Corey Kluber was not tapped for this start to give him full rest. Thus, the Indians started Trevor Bauer, who befuddled the Yankees. He was followed by strong bullpen innings by Andrew Miller and Cody Allen, resulting in only the fourth shutout the Yankees experienced all season. The Indians loaded the bases on a double, single, and walk with no outs off Sonny Gray in the second inning, but scored just one run on Roberto Pérez's double play. Jay Bruce's two-run home run in the fourth after a walk extended the Indians' lead to 3–0. After getting out of a bases-loaded one-out jam that inning, Adam Warren allowed a leadoff single in the fifth to José Ramírez, who moved to third on two wild pitches before scoring on Bruce's sacrifice fly off Jaime García for the game's final run as the Indians took a 1–0 series lead with a 4–0 win.
