The 2017 Canoe Slalom World Cup was a series of five races in canoe slalom organized by the International Canoe Federation (ICF). It was the 30th edition. Before the first World Cup race it was determined that the men's C2 class would be removed from the Olympic program. This resulted in a reduced number of participants in this event. The C2 mixed event was raced for the first time as part of the World Cup in Prague, though only 4 crews entered (3 of them Czech) and no points were awarded. The K1 cross was renamed as Extreme Kayak, but still no world cup points were awarded for the event.
