David Norman Pegler (born 2 November 1938) is a British mycologist. Until his retirement in 1998, he served as the Head of Mycology and assistant keeper of the herbarium at the Royal Botanic Gardens in Kew. Pegler received his BSc from London University in 1960, thereafter studying tropical Agaricales with R.W.G. Dennis as his graduate supervisor. He earned a master's degree in 1966, and a PhD in 1974 (both from London University). His graduate thesis was on agarics of east Africa, later published as A preliminary agaric flora of East Africa in 1977. In 1989, London University awarded him a DSc for his research into the Agaricales.
