Elisabeth of Oettingen also known as Elizabeth of Leuchtenberg (born: c. 1360; died: 9 July 1406) was a member of the House of Oettingen-Wallerstein by birth.

She was a Landgravine of Leuchtenberg by marriage and a lady in waiting for the Elector Palatine and King of Germany, Rupert.

Irmengard of Oettingen, the cousin of her grandfather, Frederick I of Oettingen, was married to Elector Palatine Adolf and was the grandmother of Rupert, the Elector Palatine and King of Germany, so Elisabeth was a third cousin of King Rupert.

She may have received her position at the Palatine court on the recommendation of her elderly great-aunt Irmengard, the elector's grandmother, who at the time lived as a Dominican nun in the Liebenau monastery at Worms.

His grave is marked with a well-preserved magnificent marble epitaph with a portrait of Leopold as a knight.
