"Alien heritage" is a speculative fiction category that centers on the consequences of having alien ancestry, artifacts, or cultural legacies woven into individual and collective identities. These stories explore characters who inherit nonhuman biology, dormant technologies, cultural memories, or social obligations—often forcing reckonings with belonging, otherness, power, and responsibility as secret lineages awaken or are discovered. Settings range from near-future Earth and frontier colonies to interstellar societies, and tones can be intimate and character-driven or sweeping and political, with plots built around mysteries of lineage, clashes between inherited alien norms and human law, colonial legacies, and the moral fallout of exploiting or preserving alien gifts. Common themes include identity and assimilation, hybridization and prejudice, the ethics of genetic and cultural inheritance, and how the past shapes future worlds.
