The Royal Crown Derby Porcelain Company is the oldest or second oldest remaining English porcelain manufacturer, based in Derby, England. The company, particularly known for its high-quality bone china, having produced tableware and ornamental items since approximately 1750. It was known as 'Derby Porcelain' until 1773, when it became 'Crown Derby', the 'Royal' being added in 1890.

Porcelain is a ceramic material made by heating raw materials, generally including kaolinite, in a kiln to temperatures between 1,200 and 1,400 °C. The greater strength and translucence of porcelain, relative to other types of pottery, arise mainly from vitrification and the formation of the mineral mullite within the body at these high temperatures. End applications include tableware, decorative ware such as figurines, toilets and washbasins, and products in technology and industry such as electrical insulators and laboratory ware.
