Suikoden II is a role-playing video game developed and published by Konami for the PlayStation video game console and the second installment of the Suikoden video game series. It was released on December 17, 1998, in Japan; on September 29, 1999, in North America; and on July 28, 2000, in Europe. The game features a vast array of characters, with over 100 recruitable characters, of which over 40 are usable in combat.

Suikoden II takes place 3 years after the events of the original Suikoden and centers on an invasion of the City-States of Jowston by the Kingdom of Highland. The player controls a silent protagonist who is the adopted son of Genkaku, a hero who saved the City-States of Jowston in a war against Highland years ago. The protagonist and his best friend, Jowy Atreides, each gain one half of the Rune of the Beginning, one of the 27 True Runes of the Suikoden setting, and become caught up in the intrigues of the invasion and the dark fate of those who bear the halves of that Rune. As with other Suikoden titles, the game also centers on the recruitment of the 108 Stars of Destiny, who together have the power to alter fate.

Suikoden II was initially released to lackluster sales and somewhat tepid critical reception, with some criticism (and lack of widespread appeal) being directed at the game's simpler and more retro 16-bit sprite visuals at a time when 3D graphics were heavily emphasized across the video game industry in the late-1990s. Since then, it in retrospect has become a cult classic of the role-playing genre and regarded one of the greatest video games ever made.

A compilation of the first two Suikoden games, Suikoden I & II, was released for PlayStation Portable in Japan on February 23, 2006. A high-definition English localization version of the compilation under the title Suikoden I & II HD Remaster: Gate Rune and Dunan Unification Wars released worldwide on March 6, 2025 for Nintendo Switch, PlayStation 4, PlayStation 5, Windows, Xbox One and Xbox Series X/S. An anime adaptation is in development.
