Coast City is a fictional city created by John Broome and Gil Kane that appears in stories published by DC Comics. It is depicted most often as the home of the Silver Age version of the superhero Green Lantern, Hal Jordan. Ferris Aircraft is one of the largest employers in Coast City.

Coast City, which first appeared in Showcase #22 in September–October 1959, was a city located in California. This made it one of the few fictional cities in the DC Universe to have a specifically given location from the start.

Coast City was usually portrayed as an analogue of San Diego or Los Angeles.Green Lantern: Rebirth identified it as being in Northern California, though recent issues of Green Lantern listed it as being twenty miles from Edwards Air Force Base.

In the 1990s, Coast City was destroyed, with nearly all of its residents - then numbered at seven million - killed by Mongul. Mongul's gigantic ship appeared over Coast City and released thousands of spherical bombs which detonated simultaneously. It was then revealed that Mongul was doing the bidding of former astronaut Hank Henshaw, better known as the Cyborg Superman. Mongul and Henshaw built Engine City in Coast City's ashes, as part of a plot to turn Earth into the new Warworld, the two intending to strike a double blow against the recently deceased Superman by claiming his world for themselves and framing him as the agent responsible for his planet's destruction. This plan was stopped by the real Superman after his resurrection, with the help of Superboy, Steel, and Hal Jordan, who had just returned from space to find his home destroyed.
