The 1975 Baltimore Orioles season concluded with the ball club finishing 4+1⁄2 games behind the Boston Red Sox in second place in the American League East with a 90–69 record.
The team stayed in playoff contention until a doubleheader sweep by the New York Yankees at Shea Stadium on the penultimate day of the regular season on September 27.
[1] Both the Orioles and Red Sox played less than a full 162-game schedule (159 and 160 respectively) primarily due to heavy rainfall across the Eastern United States in the wake of Hurricane Eloise.
The regular season would have been extended two days had the divisional title race not been decided by September 28, with the Orioles hosting the Chicago White Sox in a single night game and the Detroit Tigers in a twi-night doubleheader and the Red Sox twice playing the Yankees at Shea simultaneously.
