The Thraliana was a diary kept by Hester Thrale and is part of the genre known as table talk. Although the work began as Thrale's diary focused on her experience with her family, it slowly changed focus to emphasise various anecdotes and stories about the life of Samuel Johnson. The work was used as a basis for Thrale's Anecdotes of the Late Samuel Johnson, but the Thraliana remained unpublished until 1942. The anecdotes contained within the work were popular with Thrale's contemporaries but seen as vulgar. Among 20th-century readers, the work was popular, and many literary critics believe that the work is a valuable contribution to the genre and for providing information about Johnson's and her own life.

Hester Lynch Thrale Piozzi, a Welsh-born diarist, author, socialite and patron of the arts, is an important source on Samuel Johnson and 18th-century English life. She belonged to the prominent Salusbury family, Anglo-Welsh landowners, and married first a wealthy brewer, Henry Thrale, with whom she had 12 children, then a music teacher, Gabriel Mario Piozzi. Her Anecdotes of the Late Samuel Johnson (1786) and her diary Thraliana, published posthumously in 1942, are the main works for which she is remembered. She also wrote a popular history book, a travel book, and a dictionary. She has been seen as a protofeminist.
