So You Think (foaled 10 November 2006) is a New Zealand-bred Thoroughbred racehorse, now majority owned by Coolmore Stud of Ireland. So You Think came to prominence through winning the 2009 and 2010 Cox Plates, Australia's premier weight for age race. His second Cox Plate win came at just his tenth career start. He started as favourite for the 2010 Melbourne Cup but finished third, in his first race past 2,040 metres.
