The 2003 Canoe Slalom World Cup was a series of five races in 4 canoeing and kayaking categories organized by the International Canoe Federation (ICF). It was the 16th edition. The series consisted of 4 regular world cup races and the world cup final.
The winner of each world cup race was awarded 30 points. Semifinalists were guaranteed at least 5 points and paddlers eliminated in heats received 2 points each. The world cup final points scale was multiplied by a factor of 1.5. That meant the winner of the world cup final earned 45 points, semifinalists got at least 7.5 points and paddlers eliminated in heats received 3 points apiece. Only the best four results of each athlete counted for the final world cup standings.
The first world cup race of the season took place at the Penrith Whitewater Stadium, Australia from 10 to 11 May.
The second world cup race of the season took place at the Segre Olympic Park in La Seu d'Urgell, Spain from 5 to 6 July.
