Group Portrait of an Unknown Family or Company (1658–1660) is an oil-on-canvas painting by the Dutch Golden Age painter Pieter de Hooch.

Three of the principal figures a grey-bearded old man in dark clothes with a black cap, and two elderly women in black with white caps and collars are seated on the righit, in front of an arbour, at a table on which stands a dish of grapes and peaches.

From the left come a man and a woman; the man is in black, with a broad-brimmed hat, and rests his right hand on his hip; the woman wears a red petticoat trimmed with gold lace, a bodice of brocade, a black hood, and pearls in her hair and ears, and holds a peach in her left hand.

Farther back in the middle of the picture stands a fair-haired young man, facing the spectator; he wears a broad-brimmed hat, a light grey doublet and riding-cloak, pale blue breeches, and black and white rosettes on his shoes.

Presented by Graf Lamberg in 1821, as a Terborch, to the Akademie der bildenden Künste, Vienna, where it is No.
