The Portrait of a Lady in Blue,[1] or Woman in Blue,[2] is an oil-on-canvas portrait of an unknown woman, executed in the late 1770s or early 1780s by the English artist Thomas Gainsborough during his fifteen-year stay in Bath, Somerset.

[2][3] Some art historians have identified its subject as the Duchess of Beaufort, daughter of Edward Boscawen.

[1] It is now in the collection of the Hermitage Museum in Saint Petersburg, to which it was left in 1916 by Alexei Khitrovo, making it the only work by the artist in Russia.
