Thomas Beagley (5 October 1789 – 21 February 1858) was an English professional cricketer. He had two brothers Henry and John who also played first-class cricket. He was arguably the most talented of the trio, playing for Hampshire, Surrey, Suffolk, England and the MCC during his 23-year playing career. Beagley was regarded as one of the greatest hitters of a ball in England in the 1820s up to the early 1830s.
