The 1966 Baltimore Orioles season involved the Orioles finishing first in the American League with a record of 97 wins and 63 losses, nine games ahead of the runner-up Minnesota Twins. It was their first AL pennant since 1944, when the club was known as the St. Louis Browns. The Orioles swept the NL champion Los Angeles Dodgers in four games to register their first-ever World Series title. The team was managed by Hank Bauer, and played their home games at Memorial Stadium. They drew 1,203,366 fans to their home ballpark, third in the ten-team league. It would be the highest home attendance of the team's first quarter-century at Memorial Stadium, and was eclipsed by the pennant-winning 1979 Orioles. This was the first season to feature names on the back of the uniforms and the first with the cartoon bird on the cap.

Offseason

Regular season

Right fielder Frank Robinson, acquired via trade from the Cincinnati Reds in the off-season, won the Triple Crown, leading the AL with a .316 average, 49 home runs, and 122 RBI. He was named winner of the American League MVP Award, becoming the first player in the history of Major League Baseball to win MVP honors in both the American and National Leagues. On May 8, 1966, Frank Robinson hit a 540-foot home run off Cleveland Indians pitcher Luis Tiant, becoming the only player to hit a fair ball out of Memorial Stadium. It cleared the left field single-deck portion of the grandstand. A flag was later erected near the spot the ball cleared the back wall, with simply the word "HERE" upon it.
