The Bishop's Barn in Silver Street, Wells, Somerset, England, was built as a tithe barn in the 15th century. It has been designated as a Grade I listed building, and scheduled as an ancient monument.

A tithe barn was a type of barn used in much of northern Europe in the Middle Ages for storing rents and tithes. Farmers were required to give one-tenth of their produce to the established church. Tithe barns were usually associated with the village church or rectory, and independent farmers took their tithes there. The village priests did not have to pay tithes—the purpose of the tithe being their support. Some operated their own farms anyway. The former church property has sometimes been converted to village greens.
