Fredericka of Saxe-Gotha-Altenburg (17 July 1715 – 2 May 1775), was a German princess of the House of Wettin and a Duchess of Saxe-Weissenfels by marriage.

Born in Gotha, she was the fifteenth of nineteen children born from the marriage of Frederick II, Duke of Saxe-Gotha-Altenburg and Magdalena Augusta of Anhalt-Zerbst.
