John Bell was a builder and architect active, especially in Durham, England, in the early- to mid-18th century. He is noted to have had a great knowledge of Gothic architecture and to have often carried out the designs of James Paine. Bell worked under Paine's direction at Alnwick Castle, Northumberland in the 1760s. He died in early 1784 and was buried at the church of St. Mary le Bow, Durham, England on 16 February that year.
