Ellen Terry as Lady Macbeth is an oil painting by John Singer Sargent, now in Tate Britain, in London.

[1] Terry's spectacular gown was designed by Alice Comyns Carr (1850–1927) and made in crochet by Ada Nettleship,[2] using a soft green wool and blue tinsel yarn from Bohemia to create an effect similar to chain mail.

[3][4] The dress has a narrow border of Celtic designs worked out in red and white stones, is hemmed on all the edges, and girt with a gold belt.

The design was inspired by a dress worn by Lady Randolph Churchill that was also trimmed with green beetle wing cases.

"[7] Oscar Wilde quipped that "Lady Macbeth seems to be an economical housekeeper and evidently patronises local industries for her husband's clothes and servant's liveries, but she takes care to do all her own shopping in Byzantium.

After Irving's death in October 1905, the painting was sold at Christie's on 16 December 1905, and bought by an agent for Sir Joseph Joel Duveen, who donated it to the Tate Gallery in 1906.
