An heir apparent is a person who is next in the line of succession to a throne or title. This means they are the most likely person to inherit the position and its associated power and responsibilities upon the death or abdication of the current holder. The term is primarily used in monarchies and other hereditary systems of succession.

The concept of heir apparent is distinct from an heir presumptive. An heir apparent has an unimpeachable right to succeed, meaning their position cannot be displaced by the birth of another individual. For example, if a king has a son, that son is the heir apparent. However, if the king has a daughter but no son, the daughter might be an heir presumptive, as the birth of a son would move her down the line of succession.

Historically, the status of heir apparent has often been associated with significant political power and influence, even before formally assuming the throne. The heir apparent may be involved in governance, military leadership, or diplomatic affairs, preparing them for their future role. The specific rules of succession, and therefore the definition and status of the heir apparent, can vary significantly between different countries and historical periods. In some systems, primogeniture, where the eldest child inherits, is the primary rule, while others may have different criteria. The clear designation of an heir apparent helps to ensure stability and prevent disputes over succession.
