The 1966 New York Yankees season was the 64th season for the Yankees. The team finished with a record of 70–89, finishing 26.5 games behind the eventual World Series champion Baltimore Orioles. New York was managed by Johnny Keane and Ralph Houk. The Yankees played at Yankee Stadium. Keane managed his final MLB game in early May, and died the following January at the age of 55.

The Yankees finished in tenth place, although arguably a "strong" tenth.^[1] It was the first time they had finished in last place since 1912, their last year at the Hilltop. The Yankees would not finish in last place again for another twenty four years.

On September 22, a paid attendance of 413 was announced at the 65,000-seat Yankee Stadium.^[2] WPIX announcer Red Barber asked the TV cameras to pan the empty stands as he commented on the low attendance. Although denied the camera shots on orders from the Yankees' head of media relations, he said, "I don't know what the paid attendance is today, but whatever it is, it is the smallest crowd in the history of Yankee Stadium, and this crowd is the story, not the game." By a horrible stroke of luck, that game was the first for CBS executive Mike Burke as team president. A week later, Barber was invited to breakfast where Burke told him that his contract would not be renewed.
