An Jung-geun (; 2 September 1879 – 26 March 1910), courtesy name (), was a Korean independence activist who assassinated Itō Hirobumi, former Prime Minister of Japan and Japanese Resident-General of Korea, in Harbin, China in 1909. An was imprisoned and executed by Japanese imperial forces at Lüshun Russo-Japanese Prison in 1910.

An is honored as a martyr by the governments of South Korea, North Korea, Republic of China and People's Republic of China, while the Japanese government regards him as a terrorist. The Catholic Church excommunicated him for the assassination; the excommunication was lifted in 1993.

Background

An's family produced many other Korean independence activists. An's cousin An Myeong-Geun () attempted to assassinate Terauchi Masatake, the first Japanese Governor-General of Korea () who executed the Japan-Korea Annexation Treaty in 1910. He failed, however, and was imprisoned for 15 years; he died in 1926. An's brothers An Jeong-Geun () and An Gong-Geun (), as well as An's cousin An Gyeong-Geun () and nephew An Woo-Saeng (), joined the Provisional Government of the Republic of Korea in Shanghai, China, which was led by Kim Ku, and fought against Japan. An Chun-Saeng (), another nephew of An's, joined the National Revolutionary Army of China, participated in battles against Japanese forces at Shanghai, and joined the Korean Liberation Army in 1940. Later, he became a lieutenant general of the Republic of Korea Army and a member of the National Assembly of South Korea.

Meanwhile, An Jung-Geun's youngest son, became a prominent businessman and Chinilpa during the Japanese occupation of Korea. He died in 1952 from tuberculosis, with his children immigrating to the United States of America after the war.
