Cúscraid, known by the epithet Mend Macha (the "stammerer" or "inarticulate one" of Macha), is a son of Conchobar mac Nessa in the Ulster Cycle of Irish mythology.
The three most popular heroes with the women of Ulster were Cúscraid, Cúchulainn and Conall Cernach. The women imitated the peculiarity of the hero they loved the most: Cúscraid's fans stammered, Conall's crooked their necks, and Cúchulainn's squinted one eye in imitation of his warp spasm.
After Conchobar's death, the Ulstermen invited his eldest son Cormac Cond Longas to succeed him as king of Ulster, but Cormac was killed before he could take the throne. It was then offered to Conall Cernach, who refused, recommending Cúscraid instead, and Cúscraid became king.
