The 1995 Seattle Mariners season was the 19th in the history of the franchise. The team finished with a regular season record of .540 to win their first American League West title, after having been down by as many as 13 games in early August. They had tied the California Angels for first place, and in the one-game tiebreaker, the Mariners defeated the Angels 9–1 to make the postseason for the first time in franchise history. In the postseason, the Mariners defeated the New York Yankees in the best-of-five American League Division Series after losing the first two games in New York, a series notable for Edgar Martínez' walk-off 11th-inning double in the fifth game. In the League Championship Series with the favored Cleveland Indians, Seattle won the opener at home and the third game on the road, but fell in six games.

On September 30 with 2 games left of season, the Mariners only needed one more win to clinch their first playoff spot in franchise history, but couldn't hold it, as they lost their final two games at Texas; the Angels won their final five games to tie the Mariners at .540, requiring a one-game playoff for the division title. Also on a five-game winning streak, the Yankees secured the new wild card berth at .540.
