Ys: The Ark of Napishtim (イースVI -ナピシュテムの匣- Īsu Shikkusu -Napishutemu no Hako-^?) is a Japanese action RPG developed and published by the Nihon Falcom Corporation, and the sixth installment in the Ys video game series. It was first released in 2003 for Microsoft Windows-based personal computers. Not counting the Eternal/Complete remakes of Ys I & II, it was the first new Ys game released by Falcom in eight years. The name Napishtim is a reference to the character Utnapishtim from the Epic of Gilgamesh.

Red-haired adventurer extraordinaire Adol Christin has finally reunited with his best pal, Dogi, and is eager to set sail for new adventures in Afroca. It seems fate has other plans for him, however, as a pirate captain named Ladoc makes him an offer he simply can't refuse: a chance to explore a dangerous, uncharted archipelago in the Atlas Ocean that may hold treasures of heretofore unseen value.
