Ane Marie Elise Toft, later Grundtvig, née Carlsen (4 August 1813 – 9 July 1854) was a wealthy Danish landowner who owned and efficiently administered the Rønnebæksholm estate near Næstved which she had inherited from her first husband following a marriage lasting less than two years.

Her manor house subsequently became one of the principal centres of Grundtvigian activity while Grundtvig became deeply devoted to Toft, treating her as his independent and spiritually equal partner.

She was brought up on the estate together with her younger sister Franziska (1817–1876), who became a historian, and her elder brother Hans (1810–1887), a politician.

[3] When she was 26, on 9 June 1840, she married Harald Peter Nicolai Toft (1812–1841) who bought the Rønnebæksholm estate a few weeks later on 16 July.

His affection for Toft grew steadily but he was unable to marry her as long as his wife Lise was living.

[7] The couple enjoyed a happy marriage, as can be seen from the love poem "Hvad er det, min Marie" he wrote for her.

After giving birth to their son Frederik on 15 May, she died of breast cancer two months later on 9 July 1854 in Copenhagen.
