Phelps, the most decorated Olympian of all time, will also not represent the United States at the 2015 world championships in Russia next August, USA Swimming said in a statement.
The suspension means Phelps will be unable to compete in USA Swimming-sanctioned events for six months, and will not be eligible to swim again until March, 2015.
Phelps was arrested for drunk-driving on September 30 in Baltimore. He was also charged with excessive speed and crossing double lane lines. Police said he was driving 84 mph in a 45-mph zone.
