The publisher's editor-in-chief Axel Alonso told CBR that Macchio is stepping down, but informed fans that they can expect to see him return to writing in the future.
"After 35 years of distinctive service, senior editor Ralph Macchio is retiring," he said. "Ralph's a living legend who's edited some of the most important titles we've ever published - from Frank Miller's Daredevil to Walter Simonson's Thor to the early 'Ultimate' line to the Stephen King series.
"He's also one of the world's true gentlemen - and I mean that from the bottom of my heart - and a master impersonator whose 'Tom Brevoort' has to be seen to be believed. While Ralph's closing the door on his editing work, he's opening the door to another - expect to see him back behind the writer's desk, soon."
Tributes to Macchio from Marvel creators flooded in on Twitter in the wake of the announcement. "Congratulations to Ralph Macchio, who was always wonderful to me! What an amazing career he's had a @Marvel! You'll be missed, Ralph," wrote David Gallaher.
Brian Bendis added: "In honour of Ralph Macchio at the next retreat I will be reading the NYT and muttering under my breath."
Macchio joined Marvel Comics in the late 1970s. He became an editor for the publisher in 1981.
