Happy Harbor is a small New England municipality located in the state of Rhode Island on the east coast of the United States of America. While a center of commerce and culture,


Happy Harbor was the location of the Justice League's first secret headquarters in Mount Justice. When the location was compromised, the League moved to a new location.


Years later, it was revived for a covert operations team composed of Robin, Aqualad, Kid Flash, Superboy, and Miss Martian. While the team was out flying in Miss Martian's Bio Ship, Red Tornado learned an emergency alert was triggered at the Happy Harbor Power Plant. The team investigated covertly and discovered it was attacked by a new villain named Mr. Twister. Their battle caused much property damage to the plant, harbor, and city. On August 8th, 21:53 EDT, Young Justice set up a perimeter around Happy Harbor High School, home of the Hornets, to safeguard Dr. Serling Roquette while she completed a virus to neutralize the Utility Fog. Upon an incursion by Cheshire, the team moved Roquette across the town to the Sandbar Internet Cafe while Miss Martian posed as Roquette at another location.
