A category that a label can belong to. For example:
In a binary classification model that detects spam, the two classes might be spam and not spam.
In a multi-class classification model that identifies dog breeds, the classes might be poodle, beagle, pug, and so on.

See Classification in Machine Learning Crash Course for more information.
