Dominic Marquard, Prince of Löwenstein-Wertheim-Rochefort (7 November 1690 – 11 March 1735) was the second Prince of Löwenstein-Wertheim-Rochefort.
He was the sixth son and ninth child of Maximilian Karl Albert, last Count and first Prince of Löwenstein-Wertheim-Rochefort (1656 - 1718), and his wife Countess Maria Polyxena Khuen von Lichtenberg und Belasi (1658 - 1712). He was named after Marquard Sebastian von Schenk von Stauffenberg, (1644–1693) Prince-Bishop of Bamberg, who was his godfather.
On 28 February 1712, he married Landgravine Christine of Hesse-Wanfried (1688 - 1728) a daughter of Charles, Landgrave of Hesse-Wanfried by his second wife Countess Juliane Alexandrine of Leiningen-Dagsburg. Since his older brother had already died, unmarried and without children, at that time he was already Hereditary Prince. Dominic Marquard and Christine had thirteen children, nine of whom survived to adulthood:
In 1718, he succeeded his father, and acquired various possessions that should influence the history of the House of Löwenstein-Wertheim; in 1720 the Lordship of Haid and its castle in Bohemia, in 1721 the small market town Kleinheubach from the possession of the Counts of Erbach and 1730 the Lordship of Rosenberg in Baden, which derived the Catholic line of the family.
On 17 July 1728, the wife died in childbirth. Dominic died in 1735, in Venice, where he had gone to attend the Carnival in disguise, and was buried there, but his heart was moved to the church of Wertheim.
