John Ash (29 June 1948 – 3 December 2019) was an expatriate British poet and writer. His lifelong interest in Byzantium (especially its architecture) was a major theme which ran through his poetry, fiction and travel writing, along with family, friends and the three major cities he has lived in. As well as his books (largely published by Carcanet), his work has appeared in The New Yorker, The New York Times, The Village Voice, The Washington Post and Paris Review.
