The Volvo International, also known as the Pilot Pen International, was a professional tennis tournament played on clay courts from 1973 to 1984 and on outdoor hard courts from 1985 to 1998. It was first held at the Mount Washington Resort in Bretton Woods, New Hampshire in the United States in 1973 after Rod Laver had run a successful summer camp there. The International was originally part of the Grand Prix tennis circuit until the formation of the ATP Tour in 1990, when it became part of the Championship Series until its dissolution.
