Princess Marie-Félix Bonaparte (née Marie-Félix Blanc; 22 December 1859 – 1 August 1882) was a French heiress.
Born into a wealthy French bourgeoisie family with financial holdings in Monaco and Germany, she was left with a large inheritance after her father's death.
Despite her mother's objections, in 1880 she married Prince Roland Bonaparte, a member of a morganatic branch of the House of Bonaparte.
She died from an embolism a month after giving birth to her only child, Princess Marie Bonaparte.
