David Leach (1911-2005) was an English studio potter. He was born in Japan, the eldest son of Bernard Leach and came to England in 1920. He began an apprenticeship with his father at St Ives, Cornwall, in 1930 and trained as a pottery manager at the North Staffordshire Technical College, 1935-37. He subsequently managed the Leach Pottery, changing over from a wood-burning to an oil-burning kiln.

In 1955 Leach left St Ives to set up the Lowerdown Pottery at Bovey Tracey, Devon, where he became known for his porcelain.
