To compromise is to make a deal between different parties where each party gives up part of their demand. In arguments, compromise is a concept of finding agreement through communication, through a mutual acceptance of terms—often involving variations from an original goal or desire. Extremism is often considered as antonym to compromise, which, depending on context, may be associated with concepts of balance, tolerance. In the negative connotation, compromise may be referred to as capitulation, referring to a "surrender" of objectives, principles, or material, in the process of negotiating an agreement. In human relationships "compromise" is frequently said to be an agreement that no party is happy with, this is because the parties involved often feel that they either gave away too much or that they received too little.

Defining and finding the best possible compromise is an important problem in fields like game theory and the voting system.

Research has indicated that suboptimal compromises are often the result of negotiators failing to realize when they have interests that are completely compatible with those of the other party and settle for suboptimal agreements. Mutually better outcomes can often be found by careful investigation of both parties' interests, especially if done early in negotiations.
