Princess Feodora of Leiningen (Anna Feodora Auguste Charlotte Wilhelmine; 7 December 1807 – 23 September 1872) was the only daughter of Emich Carl, Prince of Leiningen (1763–1814) and Princess Victoria of Saxe-Coburg-Saalfeld (1786–1861). Feodora and her older brother Carl, 3rd Prince of Leiningen were maternal half-siblings to Queen Victoria of the United Kingdom. She is a matrilineal ancestor of Carl XVI Gustaf of Sweden and of King Felipe VI of Spain.

Feodora was born in Amorbach in Bavaria, Germany on 7 December 1807 to Princess Victoria of Saxe-Coburg-Saalfeld and her husband, Emich Carl, Prince of Leiningen. Her father died in 1814.

On 29 May 1818, her mother remarried to Prince Edward Augustus, Duke of Kent and Strathearn, the fourth son of King George III of the United Kingdom. The following year, the household was moved to the United Kingdom since the duchess' pregnancy was coming to an end and so that the new potential heir to the British throne could be born on British soil.

By all accounts, Feodora enjoyed a very close relationship with her sister Victoria, who was devoted to her elder sister. Despite this, Feodora was eager to leave their residence at Kensington Palace permanently, as her "only happy time was driving out" with Victoria and her governess Baroness Louise Lehzen, when she could "speak and look as she liked".
