Herumor was a Black Númenórean who lived in the late Second Age. After the Downfall of Númenor, no small number of these people sailed eastward to Middle-earth, and Herumor was among them. With another named Fuinur, he settled among the Haradrim, and became a lord in the lands of the Harad.
Herumor means "Lord of the dark" in Quenya (from heru = "lord" and morë = "dark").
 Portrayal in adaptations
In the defunct Middle-earth Role Playing game from the 1980s, Herumor is given an extended history. Fuinur is then his older brother. Tolkien, however, had nothing to do with writing this history.
- ↑ Based on the ordering of events there, he appears to have taken power in the Harad at some point after the Downfall of Númenor, dating him to S.A. 3319 or later. The order of events is not entirely clear, and an argument could be made that he lived slightly earlier, but he certainly belonged to the closing centuries of the Second Age.
