From 1658 to 1660, during the Northern Wars, Maria Amalia and her family were kept as prisoners by the invading Swedes in Riga and later in Ivangorod.
She was first engaged to her first cousin William VII, Landgrave of Hesse-Kassel (1651–1670), but he died during his Grand Tour. She was then engaged to William's younger brother and heir, Charles I, Landgrave of Hesse-Kassel (1654–1730), whom she married on 21 May 1673 in Kassel.
As landgravine, she participated in the creation of the Karlsaue Park in Kassel. The Marmor fountain in the park contains a medallion by the French sculptor Pierre Etienne Monnot depicting Maria Amalia. In 1699, together with her son Maximilian, she bought Sensenstein Castle. She was described as modest, affable and pious.
Maria Amalia died in 1711 and was buried in the Martinskirche of Kassel. The village of Mariendorf in Hesse, Germany was named in her memory.
