Tanerko (3 May 1953 – 1972) was a French Thoroughbred racehorse and sire. He was unraced as a two-year-old but established himself as one of the best colts of his generation in Europe in 1956 by winning the Prix Juigne, Prix Noailles, Prix Lupin and Prix du Prince d'Orange as well as finishing third to Ribot in the Prix de l'Arc de Triomphe. He remained in training in 1957, winning the Prix du Prince d'Orange and recording other important victories in the Prix Ganay and the Grand Prix de Saint-Cloud. He was as good as ever in a five-year-old, taking the Prix d'Harcourt and repeating his 1957 wins in the Prix Ganay and the Grand Prix de Saint-Cloud. Tanerko was then retired to stud and had considerable success as a sire of winners.
