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.

Technically, the Worcester Royal Porcelain Co. Ltd. (known as Royal Worcester) was formed in 1862, and although the company had a royal warrant of appointment from 1788, wares produced before that time, as well as those produced at two other factories in Worcester, are known as Worcester porcelain. The enterprise has followed the pattern of other leading English porcelain brands, with increasing success during the 18th and 19th centuries, then a gradual decline during the 20th century, especially the latter half.
