Chibuike Rotimi Amaechi CON (born 27 May 1965) is a Nigerian politician, who served as the federal minister of transportation of Nigeria from 2015 to 2022 under the administration of President Muhammadu Buhari. He resigned to contest for Nigeria's presidency under the governing All Progressive Congress (APC). He had previously served as governor of oil-rich Rivers State, from 2007 to 2015 and earlier, as speaker of the Rivers State House of Assembly from 1999 to 2007. On 9 April 2022, Amaechi declared interest to contest in the presidential election in 2023. He polled second position in the APC presidential primaries held in June 2022 behind eventual president Bola Tinubu with 316 delegate votes against Tinubu's 1271 votes.

Amaechi was born in Ubima Community, Ikwerre Local Government Area of Rivers State to the family of the late Elder Fidelis Amaechi and Mary Amaechi. His first and last names are Igbo meaning “God is strength or power” and “who knows tomorrow” respectively. He was raised in Diobu, a densely populated neighbourhood in Port Harcourt.

Amaechi had his primary education at St. Theresa's Primary School from 1970 to 1976. He later earned his West African Senior School Certificate in 1982 from Government Secondary School, Okolobiri. Amaechi received a Bachelor of Arts degree (Honours) in English Studies and Literature from the University of Port Harcourt in 1987, where he was the president of the National Union of Rivers State Students (NURSS).

He completed the mandatory National Youth Service Corps (NYSC) in 1988, and thereafter joined Pamo Clinics and Hospitals Limited owned by Peter Odili, where he worked until 1992. He was also a director of several companies, including West Africa Glass Industry Limited and Risonpalm Nigeria Limited.

During the transition to the Third Nigerian Republic, Amaechi was secretary of the National Republican Convention in Ikwerre Local Government Area of Rivers State. Between 1992 and 1994, he was special assistant to the deputy governor of Rivers State, Peter Odili, his boss believed in Amaechi as a young man with potential in politics and brought him under his wing. In 1996, he was the Rivers State's secretary of the Democratic Party of Nigeria (DPN) caretaker committee during the transition programme of General Sani Abacha.

In 1999, he contested and won a seat to become a member of the Rivers State House of Assembly to represent his constituency. He was subsequently elected speaker of the House of Assembly. Amaechi was elected chairman of Nigeria's Conference of Speakers of State Assemblies. In May 2003, he was re-elected speaker. In 2003, when the National Assembly moved to hijack the legislative functions of the State House of Assembly as enshrined in the constitution, he and his colleagues took the matter to the Supreme Court.

As speaker, Amaechi used his close working relationship with Governor Peter Odili to increase the harmonious relationship between the executive and legislative arms of government in Rivers State, until he launched a campaign against the state government, and verbally attacked the image of the state governor, in an effort to succeed Odili as governor in 2007.

In 2007, Amaechi contested and won the People's Democratic Party (PDP) primary for Rivers State Governor in 2007. His name was substituted by the party, an action which he challenged in court. The case eventually got to the Supreme Court. He became governor on 26 October 2007, after the Supreme Court ruled that he was the rightful candidate of the PDP and winner of the April 2007 governorship election in Rivers State.
