Hedvig Mörner af Morlanda (1672–1753), was a Swedish courtier and countess, married to riksråd count Claes Ekeblad the Elder.
She was born to general baron Hans Georg Mörner and Beata Schulman.
Prior to her marriage, she served as maid of honor to the queen of Sweden, Ulrika Eleonora of Denmark, and she also became a personal friend of Princess Ulrika Eleonora, future queen.
Hedvig Mörner was known for being able to influence state affairs and make successful recommendations for public offices through her political connections, and a large correspondence is preserved bearing witness of how much, often and how successfully she performed services for supplicants.
The opposition party of Arvid Horn worked to secure the position of field marshal for their sympathizer Göran Silfverhielm.
