Frances "Fanny" Blood (1758 – 29 November 1785) was an English illustrator and educator, and longtime friend of Mary Wollstonecraft.

[1] Blood was paid by the botanist William Curtis to paint wildflowers for his book Flora Londinensis.

Blood was engaged to Hugh Skeys, a wine merchant of Dublin, but her fiancé had gone to sea to establish money that would finance their marriage.

[1] She was buried in the British Cemetery in Lisbon with her son William Skeys.

[7] Wollstonecraft was deeply affected by Blood's death, which in part inspired her first novel, Mary: A Fiction (1788).
