Anna Fredericka Philippine of Schleswig-Holstein-Sonderburg-Wiesenburg (4 July 1665 - 25 February 1748), was a German noblewoman member of the House of Oldenburg and by marriage Duchess of Saxe-Zeitz-Pegau-Neustadt.

Born in Wiesenburg, she was the thirteenth of fifteen children born from the second marriage of Philip Louis, Duke of Schleswig-Holstein-Sonderburg-Wiesenburg with Anna Margaret of Hesse-Homburg.

In addition, she had two further older half-siblings from her father's first marriage with Catharina of Waldeck-Wildungen, of whom only one survive: Dorothea Elisabeth (by her two marriages Countess of Sinzendorf, Rabutin and Marchioness de Fremonville).

In Moritzburg Castle on 27 February 1702, Anna Fredericka Philippine married Frederick Henry, Duke of Saxe-Zeitz-Pegau-Neustadt. They had two children, of whom only one survive adulthood:
