Catherine was a daughter of the Duke Henry IV of Brunswick-Lüneburg (1463–1514) from his marriage to Catherine of Pomerania (1465–1526), daughter of the Duke Erich II of Pomerania.

She married on 20 November 1509 in Wolfenbüttel Duke Magnus I of Saxe-Lauenburg (1470–1543). Her father summoned the Parliament in 1509 to collect a lady tax, because he found himself unable to pay the dowry alone. Only after long negotiations, did the Parliament grant three rounds of real estate tax, to generate for money for a dowry and jewels for the princess.

Catherine was a strict Catholic with close ties to her relative in Brunswick kin. This induced Gustav I of Sweden, to marry her daughter, in an attempt to the Catholic German princes from supporting of King Christian II of Denmark.[1]

At the marriage of her eldest son, she entered into negotiations with his later mother-in-law Catherine of Mecklenburg, without the knowledge and to the detriment of the Wettin family head John Frederick of Saxony.[2]


From her marriage, Catherine had the following children:

  • Francis I (1510–1581), Duke of Saxe-Lauenburg
married in 1540 Sibylle of Saxony (1515–1592)
married in 1525 King Christian III of Denmark and Norway (1503–1559)
married in 1531 King Gustav I Vasa of Sweden (1496–1560)
married in 1547 Duke Francis of Braunschweig-Gifhorn (1508–1549)
  • Sophie of Saxe-Lauenburg (1521–1571)
married in 1537 Anthony I, Count of Oldenburg and Delmenhorst (1505–1573)
  • Ursula of Saxe-Lauenburg (1523–1577)
married in 1551 Duke Heinrich V of Mecklenburg (1479–1552)
