Lady Blanche Maud de la Poer Beresford Girouard (13 October 1898 – 29 September 1940) was an Irish journalist and writer.

She was born Blanche Maud de la Poer Beresford to Henry Beresford, 6th Marquess of Waterford, and Lady Beatrix Frances Petty-FitzMaurice on 13 October 1898 in London.

Girouard died as the result of a car accident in 1940 and is buried in Molesey Cemetery, Surrey.

A reviewer in Brisbane described the novel thus: "as to the manner of the writing there is only one verdict possible; It is a thing of beauty, the beauty of pure language, of poetic thought, and of idyllic Imagery".

The writing style of her book of stories received similar praise.
