Jean Cougar Mellencamp was a dish in the 24th century. It was served as "flank of cougar, captured by ten aquanauts, with coffee fraiche. Served without the purple flowers or the yellow boat".
It was offered on the menu at the French Café des Artistes in Paris, France on Earth. In 2364, Captain Jean-Luc Picard visited the holographic recreation of this café including the menu. (TNG: "We'll Always Have Paris")
The name of this dish was an in-joke from the art department, an apparent reference to John Cougar Mellencamp.
