Princess Louise of Hesse-Darmstadt (Louise Henriette Karoline; 15 February 1761 – 24 October 1829), was the first Grand Duchess of Hesse and by Rhine by marriage.

Louis I, Grand Duke of Hesse (14 June 1753 – 6 April 1830) was Landgrave of Hesse-Darmstadt (as Louis X) and later the first Grand Duke of Hesse and by Rhine.

Louis was the son of Louis IX, Landgrave of Hesse-Darmstadt, and succeeded his father in 1790. He presided over a significant increase in territory for Hesse-Darmstadt during the imperial reorganizations of 1801–1803, most notably the Duchy of Westphalia, hitherto subject to the Archbishop of Cologne. Allied to Napoleon I of France, Louis in 1806 was elevated to the title of a Grand Duke of Hesse and joined the Confederation of the Rhine, leading to the dissolution of the Empire. At the Congress of Vienna in 1814/15, Louis had to give up his Westphalian territories, but was compensated with the district of Rheinhessen on the left bank of the Rhine. Because of this addition, he amended his title to Grand Duke of Hesse and by Rhine.
