Serranus Clinton Hastings (November 22, 1814 – February 18, 1893) was a 19th-century politician and a prominent lawyer in the United States. He studied law as a young man and moved to the Iowa District in 1837 to open a law office. Iowa became a territory a year later, and he was elected a member of the House of Representatives of the Iowa Territorial General Assembly. When the territory became the state of Iowa in 1846, he won an election to represent the state in the United States House of Representatives. After his term ended, he became Chief Justice of the Iowa Supreme Court. He resigned after one year in office and moved to California. He was appointed the California Supreme Court as Chief Justice a few months later. He won an election to be Attorney General of California, and assumed office shortly after his term as Chief Justice ended. He began practicing law again as Attorney General. He earned a small fortune with his law practice and used that fortune to finance his successful real estate venture. In 1878, he founded the Hastings College of the Law with a donation of US$100,000.
