Magdalene Charlotte Hedevig Schimmelmann (10 August 1757 – 2 December 1816) was a Danish noblewoman and salonist.

On 25 May 1782, she married the statesman Count Ernst Heinrich von Schimmelmann (1747–1831).

Her salon gathered philosophers and politicians, and played a part in the country's political scene.

Her husband opened schools, which she protected, and argued for the abolition of slavery, even though they owned plantations in the Danish West Indies.

Until 1807, her political circle of ministers earned money by trading with countries involved in the Napoleonic wars, which made her salon considered to be a center of political corruption, which made it unfashionable.
