John Francis Wade (1711 - August 16, 1786) was an English hymnist. He is supposed to have written and composed the song Adeste Fideles (also known as O Come All Ye Faithful).
Either born in England or in Douay, France, Wade fled to France after the Second Jacobite rising was crushed. As a Catholic layman, he lived with exiled English Catholics in France for the rest of his life. There, he taught music and worked on church music for private use.
