Temple Grove School was a preparatory school for boys, and after 1984 also for girls, originally at Parsons Green, London, later at East Sheen, London, still later at Eastbourne, and finally at Heron's Ghyll, an estate between Uckfield and Crowborough in East Sussex. Founded before 1803 at Parsons Green, where it was known as Elm House, before it gained the name of Temple Grove, a house at East Sheen, the school survived to become one of the oldest preparatory schools in England, but in 2005 it finally closed.

William Pearson was an English schoolmaster, astronomer, and a founder of the Astronomical Society of London. He authored Practical Astronomy.
