Nicholas Horner (died 3 March 1590) was an English Roman Catholic layman, hanged, drawn and quartered because he had "relieved and assisted" Christopher Bales, a seminary priest. A tailor by trade, he was charged with making a jerkin for a priest. Horner maintained that the customer was a stranger and he didn't know who he was. Horner is recognized as a Catholic martyr, beatified in 1987.
