Sentry-459 is a fictional character appearing in American comic books published by Marvel Comics. It is one of series of giant humanoid robots called Kree Sentries built by the Kree.

The Kree Sentries first appeared in Fantastic Four vol. 1, #64 (Jul 1967) and was created by Stan Lee and Jack Kirby.

The Sentries' main purpose is to stand guard over military outposts and depots throughout the Kree Empire. Sentry-459 accompanied a Kree scientific party that journeyed to Earth to experiment on sub-humans (which in turn created the race the Inhumans). When the Kree left Earth, Sentry 459 remained to monitor Inhuman progress, so that the Kree could later use them as a militia force. Sentry-459 remained inert but observing until activated by the superheroes the Fantastic Four, who fought it to a standstill. Considering itself defeated when the Fantastic Four escaped, the Sentry sent a signal to the Kree alerting them to the presence of meta-humans on Earth and then deactivated itself (the Kree Ronan the Accuser investigates the signal and battles the Fantastic Four soon after).

The Sentry is then transported by the U.S. Army to Cape Canaveral, where it is reactivated by the Kree Colonel Yon-Rogg, the leader of the Kree expedition now investigating Earth. Yon-Rogg hopes the Sentry will kill the hero Captain Marvel, another member of expedition. Mar-Vell. However, manages to defeat it.

Ronan the Accuser later reactivates the Sentry and uses it in an attempt to reverse the course of evolution on Earth, but it is once again defeated by Mar-Vell. The Kree agents attempt to retrieve the Sentry but are driven off by spy agency S.H.I.E.L.D.. The Sentry is seen again when activated by the Super-Adaptoid, who uses the robot as part of his team Heavy Metal in a bid to destroy the superhero team the Avengers. It returned in the Blackwulf series, having been found by Ultron, and joins the Underground Legion but is eventually destroyed in the series finale.
