Alloparenting (or alloparental care) is a term for any form of parental care provided by an individual towards young that are not its own direct offspring. These are often called "non-descendant" young, even though grandchildren can be among them. Among humans, alloparenting is often performed by a child's grandparents and older siblings. Individuals providing this care are called by the neutral term "alloparent" (or "helper").
Alloparental care encapsulates a diverse range of parenting systems across a range of animal groups and social structures. The alloparent–young relationship can be mutualistic or parasitic, and between or within species. Cooperative breeding, joint brood care, reciprocal allonursing, brood parasitism and cuckoldry represent situations in which alloparenting plays a role.
