This is a list of John Constantine's lovers that have appeared in just one story (even if that story is spread over more than one issue). They have been collected in alphabetical order by surname (where applicable). More prominent lovers receive their own wiki page and can be found in the 'Lovers' category (see the link at the bottom of this page).
Ana[]
Ana was a young woman from London whom John saw for a very brief period. The couple went to Ibiza for a summer holiday, but John's bad reaction to pills, coupled with his inability to tear himself away from supernatural trouble Chas found himself in in London, led to her dumping him at the airport.
