Gerdur was the giantess wife of the Norse god Freyr and a daughter of Gymir. She was the personification of soil fertility. Her brilliant, naked arms illuminated air and sea.

The account of her wooing is given in the poem Skirnismál. She never wanted to marry Freyr, refused his proposals (delivered through Skirnir, his messenger) even after bringing her eleven golden appless and Draupnir. Skirnir finally threatened to use Freyr's sword to cover the earth in ice. She agreed to marry him.
