Jan Weenix or Joannis Wenix (between 1640/1649 – 19 September 1719 (buried)) was a Dutch painter. He was trained by his father, Jan Baptist Weenix, together with his cousin Melchior d'Hondecoeter. Like his father, he devoted himself to a variety of subjects, but his fame is chiefly due to his paintings of dead game and of hunting scenes. Many pictures in this genre formerly ascribed to the elder Weenix are now generally considered to be the works of the son.
