Royal Worcester is a porcelain brand based in Worcester, England. It was established in 1751 and is believed to be the oldest or second oldest remaining English porcelain brand still in existence today, although this is disputed by Royal Crown Derby, which claims 1750 as its year of establishment. Part of the Portmeirion Group since 2009, Royal Worcester remains in the luxury tableware and giftware market, although production in Worcester itself has ended.

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.
