New Yankee Stadium is the new ballpark for the New York Yankees, currently under construction. The new ballpark will retain the Yankee Stadium moniker held by the current stadium. It is being built on the current site of Macombs Dam Park in the New York City borough of the Bronx, across the street from the current Yankee Stadium, which it will replace. The existing stadium opened in 1923 and the New Yankee Stadium is set to open in 2009.

Groundbreaking ceremonies for the stadium took place on August 16, 2006, the 58th anniversary of Babe Ruth's death, with team owner George Steinbrenner, then-Governor of New York George Pataki, and Mayor of New York City Michael Bloomberg among the notables donning Yankees hard hats and wielding ceremonial shovels to mark the occasion. The new facility has a planned 2009 opening, coinciding with the opening of Citi Field, future home of the New York Mets. At a total cost of 1.3 billion dollars, it is the most expensive stadium ever built in the United States .
