Grace Aguilar (2 June 1816 – 16 September 1847) was an English novelist and writer on Jewish history and religion. As a child she showed great interest in history, especially Jewish history. The death of her father lead to her writing to support herself.
In 1842 she published Spirit of Judaism, in defence of her faith and its professors; and, in 1845, published The Jewish Faith and The Women of Israel in the United States. She is, however, best known by two of her novels, Home Influence (1847) and A Mother's Recompense. (1850).
In 1847 Aguilar's health began to deteriorate and she died that year in Frankfurt.
