Sir Wyke Bayliss FSA RBA (21 October 1835 – 5 April 1906) was a British painter, author, and poet. He almost exclusively painted interiors of British and European churches and cathedrals, and was known in the late Victorian era as an academic authority on art. From the start of his career Bayliss' main interest was in depicting architecture, finding "infinite charm" in the "infinite variety of the aspect of a Cathedral interior".
