List of female hereditary monarchs

This is a list of female hereditary monarchs who reigned over a political jurisdiction in their own right or by right of inheritance. The list does not include female regents (see List of regents), usually the mother of the monarch, male or female, for although they exercised political power during the period of regency on behalf of their child or children, they were not hereditary monarch, and thus cannot be included in the list of female hereditary monarchs.

Each entry contains the name (with years of birth–death) and span of reign in years (where available). Where necessary, the source of inheritance right is indicated, that is, whether they succeeded from their fathers, mothers, siblings or other relatives. Cases where succession was obtained by other means (usurpation or marriage, for example) are also indicated accordingly.
