Overview
Elizabeth (Eliza) Burnett (1766 – 17 June 1790) was the younger daughter of the Scottish judge and philosopher James Burnett, Lord Monboddo, and a famous Edinburgh beauty of the late 18th century.
She is remembered as the young woman who is celebrated by the Scottish poet Robert Burns in his "Address to Edinburgh" (1786) and his "Elegy on The Late Miss Burnet of Monboddo" (1791), which Burns wrote after her early death from consumption (tuberculosis) at the age of 24.

Life
Burnett was probably born at the family seat of Monboddo House in Kincardineshire. Her mother, also named Elizabeth or Elizabethe (born Farquharson), died soon after giving birth to her.
She is said to have met the poet Burns in the foyer of Edinburgh's Canongate Theatre and to have cemented their relationship at another meeting in Aberdeen. In 1786, Burns wrote in his poem "Address to Edinburgh" that "Dear as th' raptur'd thrill of joy; / Fair B––– strikes th' adoring eye". When the poem was reprinted, Burns added in a footnote: "Fair B. is heavenly Miss Burnet, daughter to Lord Monboddo, at whose house I have had the honour to be more than once. There has not been anything nearly like her in all the combinations of beauty, grace, and goodness the great Creator has formed since Milton's Eve on the first day of her existence."
