Alcatraz Citadel, also known as Fort Alcatraz, was the original military defense and prison on Alcatraz Island, off the coast of San Francisco, California, United States. The citadel was built in 1859 as a U.S. Army military defense, and began function as a war camp in 1861 and long-term military prison in 1868. During the American Civil War, the citadel and its batteries provided an important line of defense. The island continued to develop in the 1870s and 1880s, and in 1893, the first hospital on Alcatraz opened. A new upper prison was built in 1904, but after the citadel ceased function as a military defense in 1907 and the original citadel collapsed the following year, a $250,000 concrete military prison was erected between 1910 and 1912. In 1933-4, this was modernized and became the Alcatraz Federal Penitentiary. It housed some of America's most dangerous criminals between 1934 and 1963.

Native Americans, known as Ohlone (A Miwok Indian word), were the earliest known inhabitants of the Alcatraz island before it attained its niche in history as the most secure prison for notorious criminals. Even though they avoided the island as they believed that evil spirits resided there due to the bad atmosphere they got from the place, they were using it for deporting their criminals under the tribal law to live on the island in isolation. They also gathered eggs of birds and marine food from the island. Even after the Spanish discovered the Island in 1759, and started spreading Christianity, the natives who did not want to convert used the islands as their refuge.

However, the earliest recorded owner of the island of Alcatraz is Julian Workman, to whom it was given by Mexican governor Pio Pico in June 1846, with the understanding that Workman would build a lighthouse on it. Julian Workman is the baptismal name of William Workman, co-owner of Rancho La Puente and personal friend of Pio Pico. Later in 1846, acting in his capacity as Military Governor of California, John C. Fremont, champion of Manifest Destiny and leader of the Bear Flag Republic, bought the island for $5,000 in the name of the United States government from Francis Temple. In 1850, President Millard Fillmore ordered that Alcatraz Island be set aside specifically for military purposes based upon the U.S. acquisition of California from Mexico following the Mexican-American War. Fremont had expected a large compensation for his initiative in purchasing and securing Alcatraz Island for the U.S. government, but the U.S. government later invalidated the sale and paid Fremont nothing. Fremont and his heirs sued for compensation during protracted but unsuccessful legal battles that extended into the 1890s.
