Peter Marié (c. 1826 – January 13, 1903) was an American socialite, philanthropist, and collector of rare books and miniatures from New York City.

[1] His grandfather was assassinated during a native uprising in Santo Domingo, at which point his grandmother brought Peter's mother and two aunts to New York City.

[3] His paternal grandfather was maître de port (harbour master) in Cap-Francais in the French West Indies who died in 1792 from an accidental drowning.

[1][5] Upon his retirement, Marié, "a man of cultivated tastes who inherited a sufficient fortune to indulge them at a comparatively early age," became a socialite in New York.

[1][7][8] These included Edith Minturn Stokes, Hope Goddard Iselin, Emeline Winthrop, Emily Post, Frances Cleveland, Maude Adams, Anna Hall Roosevelt, and many others.

[5] He intended to leave his collection of miniatures to the Metropolitan Museum of Modern Art, but his offer was turned down in February 1903.
