Nubility is the state of being marriageable. In a given society, the level of nubility (those eligible for marriage), compared to the level of nuptiality (state of being married) provides important information regarding its demography.

In a physical anthropology or biomedical context, nubility sometimes refers to the attainment of regular ovulation and fertility.
