The Oakland Athletics' 1995 season was the team's 28th in Oakland, California. It was also the 95th season in franchise history. The team finished fourth in the American League West with a record of 67–77.
The Athletics, for a third consecutive year, found themselves mired in mediocrity. As had been the case in both 1993 and 1994, an average-to-poor offense (headlined by Mark McGwire, Rickey Henderson, and Rubén Sierra) was sabotaged by one of the league's worst pitching staffs. For a third consecutive season, no Athletics starter posted an earned run average (ERA) of less than 4.50; only one such starter, Todd Stottlemyre, managed to record double-digit wins in the strike-shortened campaign.
The Athletics, despite their weak pitching, managed to contend in the first half of the season. On July 1, a win over the division-leading California Angels brought them within 1.5 games of first place; it also ran their record to a surprising 34–28. As had been the case in 1994, the A's followed their surprising start with a prolonged slump; between July 2 and August 15, the team went only 13–28. The collapse, along with an Angels surge (the Angels went 30–11 over the same span) left the A's 17.5 games out of first place. As had also been the case in 1994, Oakland mounted a dramatic comeback; an Angels collapse, combined with a surge of their own, allowed them to pull within five games of first place on September 20. The September 20th victory would be their last, as Oakland lost each of the regular season's final nine games. They finished the campaign eleven games behind the AL West champion Seattle Mariners.
The Athletics' on-field mediocrity, however, contained a few bright spots. Mark McGwire clubbed 39 home runs in a mere 104 games; he would hit at least 50 in each of the four subsequent seasons. The 1995 season also saw the debut of future superstar Jason Giambi. Giambi, in his first major league season, batted .256 with six home runs in 54 games. Lastly, the season was Tony La Russa's last as Oakland's manager. He, along with most of the Athletics' assistant coaches, would join the St. Louis Cardinals in 1996.
