In psychology, as well as other social and behavioral sciences, aggression (also called combativeness) refers to behavior between members of the same species that is intended to cause pain or harm. Predatory behavior between members of one species towards another species is also described as "aggression." To exhibit aggression towards members of another species is common, such as in these examples: "Lions are aggressive hunters of antelopes," and "Eagles are aggressive hunters of small mammals."

Aggression takes a variety of forms among human beings, and it can be physical, mental, or verbal. Aggression should not be confused with assertiveness.

There are two broad categories of aggression. These include hostile, affective, or retaliatory aggression and instrumental, predatory, or goal-oriented aggression.
