Countess Johanna of Hanau-Münzenberg (1610 – 13 September 1673) was a daughter of Count Albert of Hanau-Münzenberg-Schwarzenfels and Countess Ehrengard of Isenburg (1577 – 1637).
Hanau-Münzenberg-Schwarzenfels was a cadet branch of Hanau-Münzenberg.
Johanna of Hanau-Münzenberg married twice: The sources point out that the countess brought in little to the marriage.
[2] Due to the Thirty Years' War, the lineage Hanau-Münzenberg-Schwarzenfels had become impoverished.
Seemingly in 1633, the family had to escape from the Burg Schwarzenfels, first to Worms and later to Strasbourg where they struggled with financial problems.
