Marie Hedwig Auguste of Sulzbach (German: Marie Hedwig Auguste von Sulzbach; born: 15 April 1650 in Sulzbach; died: 23 November 1681 in Hamburg) was a Countess Palatine of Sulzbach by birth and by marriage, Archduchess of Austria and by her second marriage, Duchess of Saxe-Lauenburg.

Hedwig was a daughter of the Duke and Count Palatine Christian August of Sulzbach (1622–1708) from his marriage to Countess Amalie of Nassau-Siegen (1613–1669), daughter of Count John VII of Nassau-Siegen.

She was married on 3 June 1665 per cura in the court chapel of Sulzbach to Archduke Sigismund Francis of Austria-Tyrol (1630–1665), who after his brother's unexpected death had resigned from his ecclesiastical positions in order to marry. The marriage was never consummated: while travelling to meet his bride, the Archduke fell seriously ill and died in Innsbruck twelve days after the marriage.

Hedwig's second marriage, in Sulzbach on 9 April 1668, was with Duke Julius Francis of Saxe-Lauenburg (1641–1689). Her father had a memorial stone erected in the Sulzbach parish church to commemorate the event.^[1] Hedwig had been assured an annual income of 20000guilders at her first marriage; Julius Francis made a deal with the imperial court, in which Hedwig would receive a lump sum instead.

Hedwig died in 1681 and was buried in the White Castle at Ostrov (German: Schlackenwerth).

• Anna Maria Theresia (1670–1671)

married firstly in 1690 Count Palatine Philip William of Neuburg (1668–1693)
