Elizabeth Ogilvy Benger (baptised on 15 June 1775 at West Camel, Somerset, died on 9 January 1827 in London) was an English biographer, novelist and poet.
Elizabeth was the daughter of John Benger or Benjey and his wife Mary, née Long. Her father was a tradesman in Wells, but he became a Royal Navy purser in 1782 and the family lived mainly in Chatham, Kent until 1797. According to her fellow writer Lucy Aikin, Elizabeth early showed "an ardour for knowledge, a passion for literature." She was allowed at the age of twelve to attend a local boys' school to learn Latin, and in the following year had a poem published called The Female Geniad. This featured "female theologians, scholars, and preachers such as Cassandra del Fides, Isabella of Barcelona, and Issona of Verona, alongside Cornelia, as historic women to inspire 'the British fair' of her day." It was preceded by a customarily apologetic preface that "deploys innocence with great sophistication", as recent commentators put it. "The voice [of the poem]... is the voice of cultural authority."
Impoverished after the death of her father in 1796, the family moved to Devizes, Wiltshire and then to London in 1802, where Benger made the acquaintance of several literary figures. These included the novelists Jane and Anna Maria Porter, and the poet Caroline Champion de Crespigny, a former mistress of Lord Byron. She later became known to John Aikin and his daughter Lucy, the poet and children's writer Anna Laetitia Barbauld, Sarah Wesley, the writer daughter of the prominent Methodist Charles Wesley, and the novelist and actress Elizabeth Inchbald. She made a poorer impression on Charles and Mary Lamb, and on the diarist Henry Crabb Robinson, who described her as "ludicrously fidgety" at a party where Wordsworth was present.
