Lee Myung-bak, South Korean businessman and politician, 10th President of South Korea
Lee Myung-bak (Korean: 이명박; Hanja: 李明博; ; Korean: [i.mjʌŋ.bak̚]; born 19 December 1941) is a former South Korean businessman-turned-politician who served as the tenth president of South Korea from 2008 to 2013. Before his presidency, he was the CEO of Hyundai Engineering and Construction, and the mayor of Seoul from 2002 to 2006.

He is married to Kim Yoon-ok and has three daughters and one son. His older brother, Lee Sang-deuk, is a South Korean politician. He is a Christian attending Somang Presbyterian Church. Lee is a graduate of Korea University and received an honorary degree from Paris Diderot University in 2011.Lee altered the South Korean government's approach to North Korea, preferring a more hardline strategy in the wake of increased provocation from the North, though he was supportive of regional dialogue with Russia, China and Japan. Under Lee, South Korea increased its visibility and influence in the global scene, resulting in the hosting of the 2010 G-20 Seoul summit. However, significant controversy remains in Korea regarding high-profile government initiatives which have caused some factions to engage in civil opposition and protest against the incumbent government and President Lee's Saenuri Party (formerly the Grand National Party). The reformist faction within the Saenuri Party is at odds against Lee. He ended his five-year term on 24 February 2013, and was succeeded by Park Geun-hye.

On 22 March 2018, Lee was arrested on charges of bribery, embezzlement, and tax evasion alleged to have occurred during his presidency. Prosecutors accused Lee of receiving bribes totaling 11 billion won and channeling assets of 35 billion won to an illicit slush fund. Shortly before his arrest, Lee posted a handwritten statement on Facebook denying the charges. Lee's arrest occurred roughly a year after the arrest of former president Park Geun-Hye, who was arrested on charges stemming from the 2016 South Korean political scandal. Lee was convicted on 5 October 2018 and sentenced to 15 years in prison. On 29 October 2020, the Korean Supreme Court upheld a 17-year sentence against Lee given to him by an appellate court.
