Gustav, Hereditary Prince of Sayn-Wittgenstein-Berleburg (Gustav Frederik Philip Richard; born 12 January 1969 in Frankfurt-am-Main, Germany), is the eldest child and only son of Princess Benedikte of Denmark and Richard, 6th Prince of Sayn-Wittgenstein-Berleburg.
Prince Gustav is the Hereditary Prince of Sayn-Wittgenstein-Berleburg, the senior branch of the formerly princely house of Sayn. He resides at Schloss Berleburg-Wittgenstein in the town of Bad Berleburg, in North Rhine-Westphalia, Germany, with his parents, Prince Richard of Sayn-Wittgenstein-Berleburg and Princess Benedikte of Denmark. He has two sisters, Princess Alexandra of Sayn-Wittgenstein-Berleburg and Princess Nathalie of Sayn-Wittgenstein-Berleburg.
The principality and princely title of Sayn-Wittgenstein-Berleburg descended, historically, according to semi-Salic primogeniture. If the unmarried and childless Gustav dies without legitimate issue, the family heritage devolves upon his father's younger brother, Prince Robin zu Sayn-Wittgenstein-Berleburg. He resides with his partner, Carina Axelsson.
Gustav was formerly engaged to be married to Elvire Pasté de Rochefort, with the engagement being announced on 16 August 2000 and wedding planned for 12 May 2001 in Paris. The wedding did not occur. It was announced on 16 July 2001.
He is the godfather of Count Richard von Pfeil und Klein-Ellguth, son of his sister Alexandra, Konstantin Johannsmann, son of his second sister Nathalie, and Prince Vincent of Denmark, son of his cousin the Crown Prince of Denmark.
