Lacey Green is a village and civil parish in Wycombe district near Princes Risborough, in Buckinghamshire, England. It is in the Chiltern Hills above the town. It was home to Heston Blumenthal - whose parents used to own many local (to this area) amusement arcades. RAF Bomber Command commandeered some agricultural land for an airfield during World War II. The land has now reverted to agriculture, the school playing field and the village sports ground. The hamlet was known as Leasy Green in the early 19th century. It is twinned with Hambye in France.
