Ephesus continues to be the lead contender for the author's location. Not only does tradition situate it there, but another writing associated with the Johannine corpus, the book of Revelation, is directed toward an audience in Asia Minor (Rev 1.4). Other suggestions include Palestine (especially for those looking for an early provenance) and Alexandria (because the Gospel was popular with Gnostic thinkers living in Egypt).
