Princess Margravine Albertina Frederica of Baden-Durlach (3 July 1682 – 22 December 1755) was a German princess. She was the daughter of Frederick VII, Margrave of Baden-Durlach and his wife Duchess Augusta Marie of Holstein-Gottorp. She married Christian August of Holstein-Gottorp, Prince of Eutin.

On 2 September 1704, she married Christian August of Holstein-Gottorp, Prince of Eutin.

In 1726, her husband died, and her eldest son became monarch. One year later, he died childless and her youngest son, Adolf Frederick, ascended the throne. Adolf Frederick was a minor, but was allowed to govern "with his mother's support" and guidance.^[1] She also gave him her estates Stendorf, Mönch-Neversdorf and Lenzahn to provide him with an income.^[1]

Through her paternal grandmother, Countess Palatine Christina Magdalena of Zweibrücken, a sister of King Charles X of Sweden, Albertina Frederica descended from the Swedish royal house, which is why her son in 1743 could be elected as the heir to the Swedish throne.
