Harriet Kravitz

 is Abner Kravitz's sister and is unmarried. Harriet moved in with her brother temporarily to keep house while Gladys was away visiting her mother.

Harriet fell out of a tree house when she was six years old. Ever since then Abner has been telling her that she needs glasses.

Harriet is very close with her sister-in-law and believes everything Gladys tells her about Samantha Stephens. Like Gladys, she is a snoop and spies before she knocks at the Stephenses' door.

She first met Samantha when Samantha was painting a rocking chair. Harriet dropped by to return a sauce pan that Gladys borrowed. She left, but immediately returned unannounced and saw the result of Samantha's witchcraft. Samantha had shrunk the chair to four inches tall so she could paint it more easily.
