The 1969 Houston Astros season was a season in American baseball. The team finished in fifth place in the newly established National League West with a record of 81–81, twelve games behind the Atlanta Braves. It was also the first time in their history that the Astros did not finish below .500.

Offseason

Regular season

The Astros season from August 26 to October 2 was featured in Jim Bouton's book, Ball Four. On September 19, Bouton struck out Tony Pérez of the Cincinnati Reds and made baseball history. With that strikeout, the pitching staff of the 1969 edition of the Houston Astros broke the then-National League record for most strikeouts in a season with 1,123 strikeouts. The team finished the year with 1,221 strikeouts, which stood as the National League record until 1996, when it was broken by the Atlanta Braves. They were the second team to have three pitchers with 200 strikeouts, with only the 1967 Minnesota Twins having accomplished the feat. Since then, only the 2013 Detroit Tigers have accomplished the feat.
