Kim Si-hyeon (June 9, 1883 – January 3, 1966) was a Korean independence activist and politician, also known by his pen name, Hagu (何求), and courtesy name, Guhwa (九和). As a member of the Uiyeoldan (Righteous Army), he was an ideological ally of Kim Won-bong, and was actively involved in both the Korean Communist Party in Shanghai and the Joseon Communist Party.
After graduating from the Faculty of Law at Meiji University in Japan, Kim participated in the March 1st Movement and continued his independence activities in Manchuria as part of the Uiyeoldan. He was imprisoned multiple times throughout his life. Kim was still incarcerated when Korea gained its independence, but he was released shortly after. He later served as a National Assembly member representing Andong County during the second session of the legislature.
In 1920, Kim attended the Congress of Revolutionary Organizations in Moscow, representing Korea alongside Kim Kyu-sik and Lyuh Woon-hyung. Later that year, he was involved in a plot by the Uiyeoldan to smuggle explosives into Korea for nationwide uprisings and targeted assassinations. However, he was arrested in Daegu and sentenced to 12 years in prison, serving one year at Daegu Prison.
In 1952, during a memorial event for the Korean War in Busan, Kim orchestrated an assassination attempt on President Syngman Rhee, carried out by Yu Si-tae. The attempt failed due to a gun malfunction, and Kim was subsequently sentenced to life imprisonment. He was released on April 28, 1960, after serving 7 years and 10 months, following the April 19 Revolution. Kim was then elected as a member of the 5th National Assembly.
In July 1960, he ran for president in an election held by the House of Representatives. Kim passed away on January 3, 1966.
