Nicolas de Leuchtenberg (Nicolas Alexander Fritz; born 12 October 1933, Munich) is a claimant to the Dukedom of Leuchtenberg.
He is the son of Nicolas Nicolaïevitch de Leuchtenberg and his wife Élisabeth Müller-Himmler, and is thus a direct male line descendant of Eugène de Beauharnais, first Duke of Leuchtenberg and son of Alexandre de Beauharnais and Joséphine de Beauharnais, first wife of Napoleon Bonaparte.
On 24 August 1962, he married Anne Bügge (born 1936), with whom he has two children:
Nicolas Maximilien de Leuchtenberg (1963–2002), died unmarried and without issue
Constantin de Leuchtenberg (born 1965), unmarried and without issue
