The Champion Owner of flat racing in Great Britain is the owner whose horses have won the most prize money during a season. The list below shows the Champion Owner for each year since 1894. Before 2015, the period for deciding the championship started on the day following the end of the turf Flat season and finished on the final day of the turf Flat season in the following year - for example, the 2013-14 championship ran from 10 November 2013 to 8 November 2014. From 2015, the championship has been decided by prize money won from the Guineas festival in May to British Champions Day in October.
