William Wadé Harris (c. 1860 – 1929) was a Liberian Grebo evangelist, who preached in Liberia, Côte d'Ivoire and Ghana.

[4] After Lowrie went to Cape Palmas, Harris became a (Kru-boy) crew boy on board ships which sailed on the coast of West Africa.

[5] After he returned as a crew boy on ships and settled back home as a brick mason, he married Rose Badick Farr and had six children.

His preaching produced hundreds of "Harris" churches along the Ivory Coast, although many of his followers joined established denominations, both Catholic and Protestant.

"[10] David Shank argues that Harris's work "brought about a massive break with the external practices of traditional African religions all along the coast," including the disappearance of lascivious dance, huts for isolating women during their menstrual periods and a variety of taboos about days and places.
