Aynsley China Ltd. is a British manufacturer of bone china tableware, giftware and commemorative items. The company was founded in 1775 by John Aynsley in Lane End, Longton, Staffordshire. In 1861 his grandson John Aynsley built the historic Portland Works on Sutherland Road, Longton, Staffordshire. The company is one of the last remaining manufacturers of bone china in Stoke-on-Trent.
The company's profitability made it a desirable acquisition. In June 1970 Spode put in a bid, this was then topped in July by Denbyware. Discussions then followed with Waterford Glass and a £1 million bid was agreed. In 1970 John Aynsley and Sons was taken over by Waterford and renamed Aynsley China Ltd.
In May 1997, Aynsley China was acquired by The Belleek Pottery Group in Ireland.
