Anne Kerr, Countess of Lothian

Anne Kerr, Countess of Lothian (died 1667) was a Scottish aristocrat and landowner.

She was the daughter of Robert Kerr, 2nd Earl of Lothian (d. 1624) and Annabella Campbell, daughter of Archibald Campbell, 7th Earl of Argyll (d. 1652).

On the death of her father by suicide she became Countess of Lothian in her own right. Her property seems to have been managed by the courtier Sir Robert Kerr of Ancram, and she later married his son.

She married William Kerr of Ancram (d. 1675) in 1630 or early in 1631. 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.

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.

The monogram of Anne Kerr and William Kerr with the date 1666 can be seen at Newbattle Abbey.

She died on 16 March 1667.
