Suikoden is a role-playing video game published by Konami. It is the first installment of the Suikoden series. Developed by Konami Computer Entertainment Tokyo, it was released initially in 1995 for the PlayStation in Japan. A North American release followed one year later, and a mainland European release came the following April. The game was also released for the Sega Saturn in 1998 only in Japan, and for Microsoft Windows in 1998 in Japan, South Korea and China.

The game centers on the political struggles of the Scarlet Moon Empire. The player controls a Scarlet Moon Empire general's son, who is destined to seek out 108 warriors (referred to as the 108 Stars of Destiny) in order to revolt against the corrupt sovereign state and bring peace to a war-torn land. The game is loosely based on the Chinese novel Water Margin, and features a vast array of characters both controllable and not, with over ninety characters usable in combat and many more able to help or hinder the hero in a variety of ways.

A remastered version along with a sequel of the game, Suikoden I and II HD Remaster: Gate Rune and Dunan Unification Wars, is scheduled to release for Microsoft Windows, Nintendo Switch, PlayStation 4 and Xbox One.

Suikoden plays like a traditional role-playing video game, with the player moving characters across a landscape, advancing the plot by completing tasks and talking with other characters. It has been compared to Beyond the Beyond and, more rarely, Final Fantasy VII.

The Hero may recruit up to 107 new characters to his cause, although not all recruited characters are playable characters, and the battle system in Suikoden features six person parties in combat, with each character being individually controllable, with an option to allow the characters to fight automatically. Some characters can only be recruited if the party has reached a certain experience level or found a special item.

Combat triggers through random encounters and is turn-based. Both the player-controlled party members and the computer-controlled enemy combatants select their actions before the turn commences. Characters carry out their actions in the order of their speed.

A variety of statistics determine in-game combat ability, including optimum weapon range. Weapon range requires the player to think about character placement in the standard battle formation. There are three ranges from which a character can have the ability to attack: Short, Medium and Long. Short range characters are typically swordsmen who have to be placed at the front row of the six party formation, while Medium range attacks can fight from either the front or the back row, meanwhile Long range attackers can attack from both ranges but benefit more so from fighting in the back row, usually due to either their low hit point total, their low physical defence, or both. They also benefit from being able to attack either the enemy's front row or back row in combat. If all six characters lose all their hit points and are thus incapacitated, it is game over and the player must restart from a save point. Exceptions exist for certain plot battles in which winning is optional; the player can lose and the plot continues on, albeit in a slightly different fashion.
