The 1969 American League Championship Series was the first ALCS held after Major League Baseball adopted the two-division format that season. It featured the Baltimore Orioles vs. the Minnesota Twins, with the Orioles winning the series 3–0 and advancing to the 1969 World Series, where they would lose to the New York Mets in five games. The Orioles and Twins would meet again the following year, with similar results.

This was the first of three straight appearances in the ALCS for the Orioles.
