Dr. Chris Nwabueze Ngige (born 8 August 1952) was governor of Anambra State in Nigeria from 29 May 2003 to 17 March 2006. He is a member of the Action Congresss (AC).^{[citation needed]} He was elected Senator for Anambra Central in April 2011.

Ngige was born on 8 August 1952. A medical doctor by profession, Ngige graduated from the University of Nigeria-Nsukka in 1979. He immediately went into the civil service, serving at the National Assembly and State House clinics at different times. He retired in 1998 as a Deputy Director in the Federal Ministry of Health.^{[citation needed]}

Thereafter, Ngige turned to politics, becoming a founding member of the People's Democratic Party (PDP)^{[citation needed]} By 1999, he was Assistant National Secretary and Zonal Secretary of PDP in the South East region of the country. Elected in 2003 under controversial circumstances, he quickly broke ranks with his self-styled "political godfather" after an unsuccessful attempt on 10 July 2003 to illegally remove him from office through a fabricated letter of resignation which the state assembly accepted. A Nigerian Federal Court of Appeal affirmed the nullification of Ngige's purported 2003 election victory on 15 March 2006. This was after a lower election court(election Tribunal led by Justice Nabaruma had in August 2005 nullified his 2003 victory. The court declared that Peter Obi, candidate of the All Progressives Grand Alliance (APGA) was the bona fide winner of the election.^{[citation needed]}
