William Ernest, Duke of Saxe-Weimar (19 October 1662 – 26 August 1728) was a duke of Saxe-Weimar.

Charlotte Marie of Saxe-Jena (20 December 1669, in Jena – 6 January 1703, in Gräfentonna) was a German princess member of the House of Wettin in the branch of Saxe-Jena and by marriage Duchess of Saxe-Weimar.

She was the fourth child of Bernhard II, Duke of Saxe-Jena by his wife Marie Charlotte, daughter of Henry de La Trémoille, 3rd Duke of Thouars, 2nd Duke of La Tremoille, and Prince of Talmond and Taranto. The early death of her two brothers and older sister before her own birth left Charlotte Marie as the only child of her parents for several years, until the birth of her younger brother and future 2nd Duke of Saxe-Jena, Johann Wilhelm in 1675.
