Elizabeth Maitland, Duchess of Lauderdale, 2nd Countess of Dysart, was a Scottish noblewoman. She was the eldest daughter of William Murray and his wife Catherine, the Earl and Countess of Dysart. She was raised in English court circles during the years leading up to the English Civil War and received a well-rounded education from her parents. Her first husband was Lionel Tollemache, with whom she had eleven children. In 1672, three years after Lionel's death, she married John Maitland and gained a prominent position in the restored court.

Earl of Dysart is a title in the Peerage of Scotland. It was created by King Charles I in 1643 for William Murray and has been held continuously since then by his relatives.
