Lady Joan Holland (1350 – October 1384) was Duchess of Brittany as the second wife of John IV, Duke of Brittany. She was the daughter of Joan of Kent and Thomas Holland, 1st Earl of Kent. Her mother's second husband was Edward the Black Prince, and the child of that marriage was King Richard II of England.

Joan Holland's marriage to John IV took place in London in May 1366, but without the approval of King Edward III of England, Joan's step-grandfather, who claimed overlordship of Brittany. The couple had no children.

Joan's death, in her thirties, was politically inexpedient. In 1386, two years afterwards, John IV married Joan of Navarre, later the queen of King Henry IV of England.

Mary of Waltham (10 October 1344 – September 1361), Duchess of Brittany, was a daughter of King Edward III of England and Philippa of Hainault and was the wife of John IV, Duke of Brittany, known in England as "John V" and "The Conqueror". Mary was made a Lady of the Garter in 1378.

Joan of Navarre, also known as Joanna (c. 1368 – 10 June 1437) was Duchess of Brittany by marriage to Duke John IV and later Queen of England as the wife of King Henry IV. Joan was a daughter of Charles II of Navarre and Joan of France. She served as regent of Brittany from 1399 until 1403 during the minority of her eldest son, Duke John V. She also served as regent of England during the absence of her stepson King Henry V in 1415. Four years later Henry V imprisoned her and confiscated her money and land. Joan was released in 1422, shortly before Henry's death.
