Thomas Whieldon (September 1719 in Penkhull, Staffordshire – March 1795) was an English potter who played a leading role in the development of Staffordshire pottery.
The attribution of actual pieces to his factory has long been uncertain, and terms such as "Whieldon-type" are now often used for a variety of different types of wares. Other terms reflecting the lack of certainty are "Whieldon ware" as a type, and "Astbury-Whieldon", used for early Staffordshire figures, where the two were pioneers. He worked in earthenware and stoneware, using a variety of types of body and ceramic glazes. He is especially associated with agate ware and tortoiseshell ware; in both cases Whieldon refined the techniques used, and made the types more popular.
