Sarah Wildes (née Averell; c. 16 March 1627 – 29 July 1692) was a woman executed during the Salem witch trials.

Sarah was the wife of the local judge John Wildes, and had been accused of fornication out of wedlock in 1649 and charged with wearing a silk scarf in 1663. The marriage between Sarah and John infuriated the latter's sister, Mary Gould, who used her friendship with the Putnam family to have Sarah stand trial for witchcraft, for which she was condemned to death. Sarah was hanged on 29 July 1692 along with Rebecca Nurse, Sarah Good, Elizabeth Howe and Susannah Martin.
