+A **Nash Equilibrium** is a fundamental concept in [Game Theory](/wiki/Game_Theory), representing a stable state where no player can gain by unilaterally changing their strategy, assuming the strategies of all other players remain constant. It describes a point in a [Strategic Interaction](/wiki/Strategic_Interaction) where each participant is making their best possible decision given the choices of the others.
