The 1904 U.S. Open was the tenth U.S. Open, held July 8–9 at Glen View Club in Golf, Illinois, a suburb northwest of Chicago. Defending champion Willie Anderson won the third of his four U.S. Open titles, five strokes ahead of runner-up Gilbert Nicholls. Anderson was the first to successfully defend a U.S. Open title, and he would become the first to win three straight the following year, yet to be equaled. For the first time, the U.S. Open adopted a cut after 36 holes, eliminating those more than fifteen shots behind tenth place.
