The 1970 Houston Astros season was the ninth season for the Major League Baseball (MLB) franchise located in Houston, Texas, their sixth as the Astros, their ninth in the National League (NL), second in the NL West division, and sixth at The Astrodome. The Astros entered the season having posted a record of 81–81, for fifth place and 12 games behind the division-champion Atlanta Braves.

On April 7, pitcher Larry Dierker made his second Opening Day start for the Astros, who defeated the San Francisco Giants at Candlestick Park, 8–5. The Astros' first-round draft pick in the amateur draft was pitcher Randy Scarbery, at third overall, and in the fourth round, they selected outfielder Greg Gross.

Second baseman Joe Morgan and shortstop Denis Menke represented the Astros at the MLB All-Star Game, the second career selection for both.

The Astros concluded the season with a record of 79–83, for fourth place and 23 games behind the division-champion and NL pennant-winning Cincinnati Reds in the NL West.

Third baseman Doug Rader was awarded the first of five consecutive Gold Gloves.
