Coast City is a large urban cluster located in California.
In 2010, Oliver Queen boarded a ship bound for Coast City from Hong Kong. For some time, Oliver remained in the city and began a brief stint as a vigilante, chasing around petty criminals before he was again tracked down by Amanda Waller. After drinks at a bar Amanda drugged him and forcibly returned him to Lian Yu as part of an A.R.G.U.S. mission.
McKenna Hall currently lives in Coast City with her sister, having relocated there from Star City in early 2013. Coast City is said to have the best physical therapy facility in the country, through which McKenna sought treatment after being shot by Helena Bertinelli, causing temporary paralysis.

Behind the scenes
- In the DC comics, Coast City is the home of Hal Jordan, better known as the superhero Green Lantern, who in the DC comic books is also one of Oliver and Barry's closest superhero friends.
- In the fourth season Arrow episode "Green Arrow", a pilot named "Jordan" is briefly seen when Oliver Queen and Amanda Waller are at a bar in the flashbacks. Additionally in the first season The Flash episode "Rogue Air", Barry Allen mentions Ferris Air was shutdown because one of the test pilots vanished, hinting towards a possible appearance of Hal Jordan in the show.
- Coast City's slogan "In Brightest Day, In Blackest Night; Come to Coast City, When the money is tight" is similar to Green Lantern's oath.
