David Michelinie (born May 6 1948) is an American comic book writer.

Some of his earliest work is for DC Comics's House of Secrets and a run on Swamp Thing (Vol. 1, #14-18, 21 and 22), following Len Wein and preceding Gerry Conway, illustrated by Nestor Redondo.

His most famous works include two noted runs on the Iron Man series, with co-writer (and inker) Bob Layton, in the late 1970s and early 1980s which introduced the character's serious problem with alcoholism, his specialized power armor variants and his new enmities with Justin Hammer and Victor Von Doom. He also introduced one of Stark's closest comrade, the fearless pilot, Jim Rhodes. His most noted cliffhanger was when Tony Stark was thrown out of S.H.I.E.L.D.'s helicarrier and had to don his armor completely to use its flight function before he hit the ground.

In the late 1980s, he also wrote a popular run on The Amazing Spider-Man series which featured the art of Todd McFarlane, Erik Larsen and introduced the popular supervillain Venom. Michelinie had planned to introduce Venom earlier and did include a 'teaser' scene in Web of Spider-Man #18, where Peter Parker is pushed into the path of an oncoming train. Spider-Man's 'spider sense' should have warned him, but the alien costume that is part of Venom nullified this power of Spider-Man's. This was the first of what was to be several clues leading to the reveal of Venom. Michelinie stopped writing Web of Spider-Man shortly after and was not able to continue the introduction of Venom until his time of writing on The Amazing Spider-Man, which started with issue #290.Subsequently he became the writer of probably the most famous superhero title Action Comics following Roger Stern's lengthy run which ended with #700. He also worked at Valiant Comics on the books Rai and H.A.R.D. Corps.

He also has the record of having the second longest run on The Amazing Spider-Man comic (behind only Stan Lee).

Michelinie returned to creating comics by teaming-up with Bob Layton and Dick Giordano to form Future Comics. The company closed down after only two and a half years in business in 2004.

In the credits of numerous comics, his name is misspelled as "David Micheline".
