The 1967 U.S. National Championships (now known as the US Open) was a tennis tournament that took place on the outdoor grass courts at the West Side Tennis Club, Forest Hills in New York City, United States. The tournament ran from August 30 through September 10, 1967. It was the 87th staging of the U.S. National Championships, and the fourth Grand Slam tennis event of 1967. This was the last time the U.S. National Championship was played as an amateur event; the 1968 tournament, also played at West Side Tennis Club's Forest Hills Stadium, became the first U.S.Open, following the French and Wimbledon opens earlier that year. The three doubles tournaments took place at the Longwood Cricket Club in Brookline, Massachusetts, from August 21 to 29, 1967.
