The 2003 United States Open Championship was the 103rd U.S. Open, held June 12–15 at the North Course of Olympia Fields Country Club in Olympia Fields, Illinois, a suburb south of Chicago. Jim Furyk won his only major championship, three shots ahead of runner-up Stephen Leaney. With a total score of 272, Furyk tied the record for the lowest 72-hole score in U.S. Open history, also achieved in 2000 and 1980 (and since lowered to 268 in 2011). Another record was equalled by Vijay Singh, who tied Neal Lancaster's 9-hole record of 29 on the back nine of his second round.
