Heddon-on-the-Wall came to prominence when it was revealed in February 2001 that the 2001 outbreak of Foot-and-mouth disease originated from a farm in the village. This severely affected Heddon-on-the-Wall's primary industry which is agriculture. Over the years, however, other industries have existed in Heddon-on-the-Wall. These include salmon fishing in the River Tyne, coal mining, the quarrying of sandstone and limestone, and brick making. Wylam Brewery was established at South Houghton Farm in 2000 before moving to Newcastle in 2016. A number of blacksmiths were in the village until recent times. In the 1970s there was a perfumery-manufacturing business.
