Francès Cornelia Marjolin-Scheffer (29 July 1830 – 20 December 1899) was a French artist and designer, notable for her drawings, ceramics and sculptures.

In her birth registration, her father stated her mother's name as "Maria Johanna de Nes",[2] but this is traditionally held to be a pseudonym for an anonymous woman of royal descent.

She spent much time at her father's studio on rue Chaptal in the Nouvelle Athènes in Paris, a district much-frequented by artists.

Her father's brother Arie Johannes Lamme painted her sitting at a piano in the small studio.

She died in Paris on 20 December 1899 and was buried there in the family grave at the cimetière de Montmartre.
