mid-15c., moreys daunce "Moorish dance," from Flemish mooriske dans, from Old French morois "Moorish, Arab, black," from More "Moor" (see Moor). Unknown why the English dance was called this, unless in reference to fantastic dancing or costumes (cf. Italian Moresco, a related dance, literally "Moorish;" German moriskentanz, French moresque).
