Alice Dudley, Duchess of Dudley (née Leigh; 1579 – 22 January 1669), also known as Duchess Dudley, was the second wife of the explorer Sir Robert Dudley. In 1605, after giving birth to seven daughters, she was abandoned by her husband, who went into exile in Tuscany, remarried, and eventually sold his English estates. In 1644, by way of reparation for her losses, King Charles I created Alice Dudley a duchess in her own right "for her natural life", the dukedom thus created not being heritable.
