Fisherman's Wharf was a neighborhood of San Francisco, California. The wharf was home to several piers. This neighborhood was located in the northeast corner of the city. North of the wharf was the island Alcatraz. Southeast of the wharf, in the city on Telegraph Hill, was Coit Tower.
In 1986, Fisherman's Wharf's location was depicted on a San Francisco Municipal Railway transit map. Later that year, when Hikaru Sulu flew a helicopter over San Francisco Bay, this wharf could be seen in the background. (Star Trek IV: The Voyage Home)
