Anne Kerr, Countess of Lothian (died 1667) was a Scottish aristocrat and landowner.
Her property seems to have been managed by the courtier Sir Robert Kerr of Ancram, and she later married his son.
He was the son of Robert Kerr of Ancram, later Earl of Ancram (1578–1654) and Elizabeth Murray, daughter of John Murray of Blackbarony, After the marriage, William Kerr became known as the Earl of Lothian by special grant in 1631.
[2] Sir William Kerr of Blackhope claimed the title of Earl of Lothian as nearest male heir, despite the charter granting it to Anne Kerr.
His claim was denied by the Privy Council of England in March 1632.
