The 1963 U.S. Open was the 63rd U.S. Open, held June 20–23 at The Country Club in Brookline, Massachusetts, a suburb southwest of Boston. Julius Boros won his second U.S. Open title in an 18-hole Sunday playoff with Jacky Cupit and Arnold Palmer. The U.S. Open returned to The Country Club for the first time in fifty years to celebrate the golden anniversary of Francis Ouimet's playoff victory in 1913. Boros won eleven years earlier in 1952, and won a third major at age 48 at the PGA Championship in 1968. This U.S. Open was played the week after Father's Day.
