The AT&T National is a professional golf tournament held in the Washington D.C. area during the Fourth of July weekend. The PGA Tour event is hosted by Tiger Woods and benefits the Tiger Woods Foundation. The first AT&T National was held July 5–8, 2007, at the Blue Course of the Congressional Country Club in Bethesda, Maryland. The event returned to Congressional in 2008 and 2009 and has been held midway between the U.S. Open and the British Open to ensure a strong field of competitors.

Nick Watney is the defending champion, winning in 2011 with a score of −13.

The event was officially announced on March 7, 2007, to replace The International, which tour officials had abruptly cancelled on February 8, 2007. The AT&T National does not use the Modified Stableford scoring system used by The International in Colorado.

The D.C. area hosted a regular tour event for over a quarter century. The Booz Allen Classic arrived in 1980 but was terminated after the 2006 event. Originally named the Kemper Open, it was played at Congressional from 1980–86, then moved to the nearby TPC at Avenel in 1987. Congressional hosted the tournament in 2005, while Avenel was undergoing renovations.

Eldrick Tont "Tiger" Woods (born December 30, 1975) is an American professional golfer whose achievements to date rank him among the most successful golfers of all time. Formerly the World No. 1, he is the highest-paid professional athlete in the world, having earned an estimated US$90.5 million from winnings and endorsements in 2010.

Woods turned professional in 1996, and by April 1997 he had already won his first major, the 1997 Masters. He first reached the number one position in the world rankings in June 1997. Through the 2000s, Woods was the dominant force in golf, spending 264 weeks from August 1999 to September 2004 and 281 weeks from June 2005 to October 2010 as world number one. From December 2009 to early April 2010, Woods took leave from professional golf to focus on his marriage after he admitted infidelity. His multiple infidelities were revealed by several different women, through many worldwide media sources. This was followed by a loss of form, and his ranking gradually fell to a low of #58 in November 2011. He snapped a career-long winless streak of 107 weeks when he captured the Chevron World Challenge in December 2011. As of April 8, 2012, he is ranked #8.
