Anna Cora Mowatt Ritchie (née, Ogden; after first marriage, Mowatt; after second marriage, Ritchie; pseudonyms, Isabel, Henry C. Browning, and Helen Berkley; March 5, 1819 – July 21, 1870) was a French-born American author, playwright, public reader, actress, and preservationist.

Anna Cora Mowatt played a central role in lobbying and fundraising during the early years of the Mount Vernon Ladies' Association, the oldest national historic preservation organization in the United States.

On October 6, 1834, at age 15, Anna Cora Ogden eloped with James Mowatt (1805–1851), a New York lawyer.

They moved to an estate in Flatbush, New York, where her husband encouraged her to continue her education and to write.

Her first performance was attended by Edgar Allan Poe, who wrote of her, "A more radiantly beautiful smile is quite impossible to conceive.

"[4] Her readings were popular and well attended, but her career as a reader was short lived due to respiratory problems.

On June 13, 1845, she made another career move to acting, she debuted at the Park Theatre as Pauline in The Lady of Lyons with great success.

[7] Although her next play, Armand, was published in 1847, and also received good reviews, she continued in her acting career.

Their wedding was a lavish affair, attended by President of the United States, Franklin Pierce and his Cabinet.

Anna Cora Ogden Mowatt Ritchie died in Twickenham, England, on July 21, 1870.
