Harad is a town in Saudi Arabia.
In J. R. R. Tolkien's universe of Middle-earth, Harad (Sindarin: South, in Quenya: Hyarmen) was the name for the immense lands south of Gondor and Mordor. The Men of Harad were called Haradrim "South-multitude".
Harad's tribes were divided - at least in the minds of the men of north-western Middle-earth - into those of Near and Far Harad, although there were many tribes of the Haradrim, often mutually hostile. Those of Near Harad were brown-skinned, with black hair and dark eyes, whereas the people of Far Harad had black skin.
From the latter part of the Second Age, the Men of Harad were dominated by the Númenoreans, as were many other peoples who's lands included a coastline. Shortly before the War of the Last Alliance: two Númenorean lords, for example, named as Herumor and Fuinur, "rose to great power amongst the Haradrim", but their ultimate fate is not recorded.
For many centuries of the Third Age, many Haradrim were still ruled by Black Númenórean Lords, or further north by the Kings of Gondor, but ultimately, the Harad fell under the influence of Mordor, for much of the Age.
Much of Far Harad was a jungle, although there also was a desert. In Far Harad lived the gigantic mammoth-like animals known as Oliphaunts, which were used by the Haradrim as moving war towers.
Near Harad later formed an alliance - or maybe even a coalition of some sort - with the Corsairs of Umbar, and was involved in a series of continual battles with Gondor over South Gondor or Harondor. Anciently its northern border was held to be the river Harnen, but by the time of the War of the Ring all the land south of the river Poros was under the influence of the Haradrim.
One of the leaders of the Haradrim at the time of The War of the Ring bore the standard of 'The Black Serpent', and was slain by King Theoden of Rohan at the Battle of the Pelennor Fields in T.A 3019.
After the revival of The Reunited Kingdom of Gondor and Arnor in the Fourth Age, much of the Harad may have again fallen under the rule of Gondor.
To the east of Near Harad lay the land of Khand.
