Rose Champion de Crespigny (born Annie Rose Charlotte Key; 9 November 1859 – 10 February 1935) was an English artist and author, who published many novels as Mrs Philip Champion de Crespigny.

Rose was the daughter of Admiral Sir Astley Cooper Key (who later changed the surname to Cooper-Key) and his wife, Lady Charlotte Lavinia (née McNeil).

She was born 9 November 1859 in Kensington, and she was baptised 15 December 1859 at St John's, Notting Hill.

They had four children, including Frederick Philip Champion de Crespigny (1884–1947), who inherited the baronetcy, as the 7th Baronet, the year before his death:[5]
