Roei Yellin (born September 11, 1981) is an Israeli sprint canoer who competed in the early to mid 2000s. Competing in two Summer Olympics, he earned his best finish of ninth in the K-1 1000 m event at Athens in 2004. This article discusses canoe sprint and canoe marathon, competitive forms of canoeing and kayaking on more or less flat water. Both sports are governed by the International Canoe Federation (ICF). Canoe sprint, which is referred to by the IOC as "canoe/kayak sprint", is one of the two forms of the canoeing disciplines that are featured in the Summer Olympics, the other being canoe slalom. Marathon racing is not an Olympic sport. In non-Olympic years, the main events are the World Championships.
