The Baltimore Orioles have had a rather storied history, dating back to the franchise’s roots in both Milwaukee and St. Louis. In Baltimore, however, the O’s have had much more success than in the franchise’s first two stops. Baltimore has seen the likes of Cal Ripken Jr., Eddie Murray, and Brooks Robinson, among others, call the city home. And, the town has seen plenty of playoff baseball over the years. But how many World Series titles have the Orioles won in its history? Let’s take a look at the O’s playoff successes.

When did the Orioles last win a World Series title?

The Orioles last won in 1983.

How many World Series have the Baltimore Orioles won?

The Baltimore Orioles franchise has won three World Series titles, in 1966, 1970, and 1983.

The Orioles won its first World Series title in 1966, 12 years after the team’s initial season in Baltimore. Frank Robinson, Brooks Robinson, and Boog Powell powered the team offensively, while the pitching staff was held down by starters Dave McNally and a young Jim Palmer. This season would be the start of a six-year run that would see the O’s make the Fall Classic four times.

Baltimore came up short in 1969 to the Mets, and in 1971 to the Pittsburgh Pirates. Sandwiched in between those seasons was 1970, a year that saw the Orioles win a second World Series title.

The O’s rode a 108-win season into the Postseason and followed that up with series wins against the Minnesota Twins and the NL champion Cincinnati Reds. The 1970 Orioles would feature many of the same cast of characters in the lineup, like Powell and the Robinsons. The starting pitching staff included three of the most dominant starters of that time period, McNally, Palmer, and Mike Cuellar.

The Orioles’ last World Series title came in 1983. Baltimore’s lineup was led by superstar first baseman Eddie Murray, who slugged 33 dingers and 111 RBIs that season, and a young Cal Ripken Jr.

Cal was exceptional for the O’s that season, leading the team in WAR (8.2) while showcasing his dominance with his glove and bat. Ripken Jr. led all of the Majors in 1983 in hits (211) and doubles (47) while driving in 102 runs. That season earned Ripken his first of two AL MVP awards.

Balitmore defeated the Phillies in five games to claim the 1983 crown.

The Orioles have had to deal with stiff competition in recent years in the AL East. Dating back to 2018, three AL East teams — the Yankees, Red Sox, and Rays — have won the pennant. But with a young core led by Adley Rutschman, it is possible that the O’s win it again in the near future.
