Countess Amalie Maximilianovna Adlerberg (16 June 1808 – 21 June 1888) was an illegitimate daughter of Duchess Therese of Mecklenburg-Strelitz, fathered by Bavarian diplomat Maximilian-Emmanuel Graf von und zu Lerchenfeld auf Köfering und Schönberg (1772–1809). Amalie's mother was an aunt of Empress Alexandra Feodorovna, wife of Tsar Nicholas I.
Her mother's husband, Karl Alexander Fürst von Thurn und Taxis (1770–1827), was invited by Napoleon for his new projects, and lived in Paris for years.

After her father, Graf von Lerchenfeld's death on 19 October 1809, Amalie was placed in the care of Therese's "von Sternfeld" relatives in Darmstadt (then in the Grand Duchy of Hesse), and the baby carried their surname after she was born. Amalie von Sternfeld was later brought to Regensburg, closer to Princess Therese and changed her surname to "Stargard". She was finally taken care of by the Lerchenfeld family and lived in their palace in Munich or at the family castle in Köfering near Regensburg. Finally, on 1 August 1823, the Grand Duke of Hesse gave the fifteen-year-old Amalie Stargard permission to carry the surname "von Lerchenfeld", but without rights to use the coat of arms or be listed in the family tree, which was the price for her extramarital birth.
In 1822, the fifteen-year-old beauty Amalie Stargard met young Fyodor Tyutchev, supernumerary attaché of the Russian diplomatic mission who arrived from Saint Petersburg. Young nineteen-year-old Tyutchev fell in love and the two young people shared tender romantic feelings. Tyutchev's poem Tears or Slezy () coincides with one of their dates, and most likely dedicated to Amalie. Among other poems inspired by Amalie are K N. and Ia pomniu vremia zolotoe…
