Ethan Van Sciver is an American comic book artist, best known for illustrating a number of titles including Green Lantern, Superman/Batman, New X-Men, and currently, The Flash: Rebirth. He is known for having consistently detailed rendering in his work.

Van Sciver cites Chris Claremont and Jon Bogdanove's "Fantastic Four vs. X-Men" as a strong influence, telling a group of fans at Comic-Con International that "I'm trying in my own comics to recreate the feeling I got from that four-issue miniseries."

Many of Van Sciver's most notable works have been produced in collaboration with writer Geoff Johns. Van Sciver feels he may have had a "bad influence" on the writer, working with him early on on the superhero-horror one-shot The Flash: Iron Heights. The artist described his approach on the issue as "taking well known, maybe well worn superhero concepts, make them scary, make them upsetting in some way."

For Marvel, Van Sciver produced several issues of Grant Morrison's New X-Men, starting as a two-issues-per-year fill-in artist for regular series artist Frank Quitely.

In 2004, Johns and Van Sciver brought Hal Jordan back to the DC Universe as Earth's main Green Lantern officer in the six-issue miniseries Green Lantern: Rebirth, before the duo re-launched the Green Lantern title itself with a new volume. Van Sciver's work on the Green Lantern mythos helped explain and retcon many elements of the Green Lantern story which some fans and writers found nonsensical, such as the reasons of the power rings uselessness against the color yellow, and Hal Jordan's transformation into thesupervillain Parallax.

In 2007, Johns, Van Sciver, Dave Gibbons and Ivan Reis produced the eleven-issue Sinestro Corps War across the two Green Lanternmonthly titles, the second part of a mooted trilogy of Green Lantern tales. This story launched the Sinestro Corps, the antithesis of the Green Lantern Corps, led by rogue Green Lantern Sinestro and his Qwardian yellow power ring. The series set the stage for a complete overhaul of the Lantern Corps, and introduced the emotional spectrum of power which provides energy to many different color variations of power rings.

In 2008, Van Sciver was the guest artist on an issue of Justice League of America (vol. 2) #20 (June 2008). Van Sciver's 2009 work includes the six-issue mini-series The Flash: Rebirth, and variant covers for the Green Lantern and DC Comics event, The Blackest Night.
