Canoe slalom is a high-speed competitive sport involving river rapids.

Athletes navigate decked boats through a series of hanging gates. These gates are suspended from wires stretched across the water. The goal is to complete the course in the fastest time possible. This sport requires immense skill, balance, and strength. It is one of two canoeing disciplines at the Summer Olympics. The other Olympic discipline is known as canoe sprint.

A slalom course consists of 18 to 25 numbered gates. Each gate has two poles and is color-coded. Green gates indicate a downstream direction for the paddler. Red gates indicate an upstream direction. To navigate an upstream gate, paddlers often enter an eddy. An eddy is a place where the water is flat or moving slightly upstream. This allows the athlete to turn and paddle against the main current. Downstream gates may also be placed in eddies to increase difficulty. Some gates are offset to different sides of the current to force rapid turns.

Rules are very strict to ensure precision during a run. To negotiate a gate correctly, the athlete's head and part of the boat must pass through it. If a boat, paddle, or body touches a pole, a two-second penalty is added. Missing a gate results in a much larger 50-second penalty. This penalty applies if a paddler misses a gate or goes through it the wrong way. They also receive this penalty if they go through a gate upside-down. If a competitor incurs multiple penalties on one gate, only the highest one is taken. Most elite paddlers finish a course in 80 to 120 seconds. However, difficult water can push times up to 200 seconds.

Competition formats vary depending on the event. In World Championships, athletes first complete a qualification round called the heats. The fastest 20 to 30 boats move to the semi-final. In the Olympics, the format is slightly different. Each competitor completes two runs, and only their fastest time counts for qualification. Between 10 and 40 boats move from the Olympics qualification to the semi-final. The semi-final consists of a single run on a different course. The fastest boats from that run move to the final. In the final, ranking is based only on the time of that last run.

The history of the sport began in Switzerland in 1933. Initially, racing took place on flatwater courses. The International Canoe Federation (ICF) was formed in 1946 to govern the sport. The first World Championships were held in Switzerland in 1949. For many years, these championships were held in Europe. The first North American World Championship occurred in 1979 in Canada. Canoe slalom made its Olympic debut in 1972 in Augsburg, West Germany. After a break, it returned to the Olympics in 1992 in Spain. Since 1992, it has been a regular Olympic event in many countries.

Boat technology has evolved significantly over the decades. Early folding kayaks were used from 1949 to 1963. In the 1960s, boats were made of heavy fiberglass and nylon. These boats often weighed over 30 pounds (14 kilos). The introduction of Kevlar and carbon fiber in the 1970s changed everything. These materials allowed boats to become much lighter and faster. The ICF also reduced boat widths and volumes to help boats pass through gates. In 2005, the minimum boat length was reduced from 4 meters to 3.5 meters. This change allowed for more speed and precision in modern courses. Today, high-end racing boats cost between $1,200 and $2,500.

Modern slalom often takes place in manmade environments. Most Olympic venues use concrete channels to create rapids. This trend began with the Augsburg Eiskanal in 1972. These artificial courses are often more predictable than natural rivers. There are currently six Olympic medal events. These include Men's C-1, Men's K-1, and Women's K-1. New events like Kayak Cross (KX-1) were introduced in 2024 for both men and women. Kayak cross is a unique discipline where four kayaks race at once. In this event, contact between boats is permitted, but dangerous paddling can lead to disqualification.
