Countess Palatine Dorothea of Simmern (6 January 1581 - 18 September 1631) was a Countess Palatine of Simmern by birth and Princess of Anhalt-Dessau by marriage.
Dorothea was born in Kaiserslautern, the only surviving child of the Count Palatine John Casimir of Simmern (1543–1592) from his marriage to Elisabeth (1552–1590), the daughter of Elector August of Saxony.
She married on 21 February 1595 in Heidelberg to Prince John George I of Anhalt-Dessau (1567–1618). She was his second wife. She was led to the altar by her guardian, Elector Palatine Frederick IV. Under her influence, her husband openly converted to Calvinism in 1596.[1] After his death, she retired to her widow seat Sandersleben Castle.
She was a member of the Virtuous Society under the nickname German: die Gastfreie ("the Hospitable").
Dorothea died in Sandersleben, aged 50, and was buried in the Church of St. Mary in Dessau. Her two eldest sons added a tomb stone to her grave in 1631.
From her marriage Dorothea had the following children:
