1912 U.S. National Championships (tennis)

The 1912 U.S. National Championships (now known as the US Open) took place on the outdoor grass courts at the Newport Casino in Newport, USA. The men's singles tournament ran from 19 August until 26 August while the women's singles and doubles championship took place from 10 June to 15 June at the Philadelphia Cricket Club in Chestnut Hill. It was the 32nd staging of the U.S. National Championships, and the third Grand Slam tennis event of the year. The challenge round was abolished in this edition, thus requiring all participants, including the defending champion, to play the main draw.
