Two on a Tower: A Romance (1882) is a novel by English author Thomas Hardy, classified by him as a romance and fantasy it is one of his minor works. The book is one of Hardy's Wessex novels, set in late Victorian Dorset.

Because the book defied the social norms of the day, upon release the book was called shocking, repulsive, and one critic called it Hardy's "worst yet." Hardy's biographer, Claire Tomalin, says Hardy was "writing for serialization, which drove him to pack in far too much plot," and he wrote too fast "without time to think or reconsider."

Hardy wrote in a letter to Edmund Gosse on 10 Dec 1882, "I get most extraordinary criticisms of T. on a T. Eminent critics write & tell me in private that it is the most original thing I have done...while other eminent critics (I wonder if they are the same) print the most cutting rebukes you can conceive-show me (to my amazement) that I am quite an immoral person..."
