The Champion Jockey of flat racing in Great Britain is the jockey who has ridden the most winning horses during a season. The list below shows the Champion Jockey and the number of winners for each year since 1840. The seasonal record of jockeys' winners was published for the first time in 1846. The championship was sponsored for the first time in 2009 by online casino 32Red and is currently sponsored by Stobart Group. A prize of £25,000 to the champion jockey, and £10,000 for the runner up, was also introduced as part of the 2015 changes.
