François de Bassompierre (April 12, 1579 – October 12, 1646) was a French courtier. The son of Christophe de Bassompierre (1547–1596), he was born at the castle of Haroué in Lorraine. He was descended from an old family which had for generations served the dukes of Burgundy and Lorraine, and after being educated with his brothers in Bavaria and Italy, was introduced to the court of King Henry IV of France in 1598. He became a great favourite of the king and shared to the full in the dissipations of court life. In 1600, he took part in the brief campaign in Savoy, and in 1603 fought in Hungary against the Turks for emperor Rudolf II.
