The Seattle Mariners' 1995 season was the 19th in the history of the franchise. The team finished with a regular season record of 79–66, tying the California Angels for first in the American League West. In a 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 being down 2 games to 0, a series notable for Edgar Martínez' 11th-inning double that clinched the series for the Mariners. They were subsequently defeated in the American League Championship Series by the Cleveland Indians, 4–2.

The Mariners honored the West Coast Negro Baseball League Seattle Steelheads when they wore 1946 Steelheads uniforms on September 9, 1995, at home against the Kansas City Royals. The Royals wore Kansas City Monarchs uniforms. The Mariners beat the Royals 6 to 2 in front of 39,157 fans at the Kingdome.
Randy Johnson won the Cy Young Award. The award came at the end of a banner year. Johnson (18-2, 2.48 ERA, 294 strikeouts) narrowly missed becoming the first AL Triple Crown pitcher (leading the league in wins, ERA, and strikeouts) since Detroit's Hal Newhouser accomplished the feat in 1945. His .900 winning percentage broke Ron Guidry's 1978 record, and his strikeouts per nine innings ratio of 12.35 broke the record held by Nolan Ryan.
