Uncle Mo (March 10, 2008 – December 19, 2024) was an American champion Thoroughbred racehorse who went undefeated in his two-year-old season and was named the American Champion Two-Year-Old of 2010. However, his three-year-old season was disrupted by illness, causing him to miss the Kentucky Derby. Retired to stud in 2012, he was the leading freshman sire with his first foal crop, which included 2016 Kentucky Derby winner Nyquist.
