The 2003 1000 Guineas Stakes was a horse race held at Newmarket Racecourse on Sunday 4 May 2003. It was the 190th running of the 1000 Guineas. The winner was the Cheveley Park Stud's Russian Rhythm, a Pennsylvania-bred chestnut filly trained in Newmarket, Suffolk by Michael Stoute and ridden by Kieren Fallon. Russian Rhythm's victory was the first in the race for her owner, the second for Stoute after Musical Bliss (1989) and the third for Fallon after Sleepytime (1997) and Wince (1999). The contenders The race attracted a field of nineteen runners, fifteen trained in the United Kingdom, two in Ireland and two in France. The favourite was the French filly Six Perfections who had been named European Champion Two-year old Filly in 2002 when she had won the Prix du Calvados and the Group One Prix Marcel Boussac. On her three-year-old debut she had won the Prix Imprudence at Maisons-Laffitte Racecourse in April. The other French challenger was the André Fabre-trained Intercontinental, winner of three of her four races. Ireland was represented by two runners from the Ballydoyle stable of Aidan O'Brien: Yesterday, who went on to win the Irish 1000 Guineas, and L'Ancresse, the runner-up in the Leopardstown 1,000 Guineas Trial Stakes. The Godolphin stable fielded Mezzo Soprano and Gonfilia, who had finished first and second in the UAE 1000 Guineas. The leading British-trained contender was the undefeated Soviet Song, winner of the Sweet Solera Stakes and Fillies' Mile. Other challengers included Russian Rhythm (Princess Margaret Stakes, Lowther Stakes, Cheveley Park Stakes), Tante Rose (Fred Darling Stakes) and Khulood (Nell Gwyn Stakes). Russian Rhythm had been joint-favourite for the race before performing poorly in training gallops. Six Perfections headed the betting at odds of 7/4 ahead of Soviet Song (4/1), Intercontinental (5/1), Mezzo Soprano (7/1) and Russian Rhythm (12/1).

Other horses racing prominently in the early stages were Yesterday, Casual Look, Summitville, Duty Paid, L'Ancresse, Mezzo Soprano and Gonfilia whilst most of the leading fancies were restrained towards the back of the field. Gonfilia moved into the lead approaching the final quarter-mile at which point there was a good deal of bunching and scrimmaging, with several runners
