The Stark Tower Complex is a fictional high-rise building complex appearing in American comic books published by Marvel Comics. Located in Midtown Manhattan, New York City, USA, the complex is named after its owner Tony Stark, who is the alter ego of the superhero Iron Man. The structure is composed of a 93-story Main Tower flanked by a 35-story South Building and 55-story North Building. Located at the top of the Main Tower was the Watchtower of the superhero The Sentry, but it has been replaced by Heimdall's observatory. The Main Tower is informally known as Avengers Tower, as it serves as the headquarters of the superhero team, the Avengers, similar to the Avengers Mansion. Currently, the main Stark Tower is located in Broadway, occupying the space of the Condé Nast Building.

The Stark Tower Complex was built as a world-class financial and business facility to complement the Midtown Manhattan business district. The building was completed as a gleaming beacon of modern architecture after four years of excavation and construction. It is located in the vicinity of Manhattan's Columbus Circle approximately 10 blocks north of the Baxter Building, headquarters of the superhero team the Fantastic Four.

While initially intending to use the top three floors of the Main Tower as his state-of-the-art bachelor pad, Stark gave them over to the Avengers as their base of operations after their former base, Avengers Mansion, was destroyed. Longtime caretaker of the Avengers Mansion Edwin Jarvis was asked to resume his duties in the new location. Later, when the Sentry became a member of the Avengers, his long-hidden Watchtower appeared, integrating itself atop the Main Tower, fully integrated into the building's existing architecture. Serving as both Sentry's headquarters and as the private residences of Robert Reynolds and his wife Lindy, the 20-story watchtower is operated and maintained by CLOC (Centrally Located Organic Computer), a near-sentient computer of Sentry's own design. The lower levels of the Main Tower, along with both the South and North Buildings, are largely occupied with Stark's subsidiaries and non-profit organizations.
