Pierre Ngolo (born 27 June 1954) is a Congolese politician who has been Secretary-General of the Congolese Labour Party (PCT) since August 2011. He was First Secretary of the National Assembly of Congo-Brazzaville from 2002 to 2012.
Ngolo was born at Etoro, located in the Gamboma District of Plateaux Region. As a young man, he was active in the Congolese Socialist Youth Union, the PCT's youth wing. He attended the Marien Ngouabi University in Brazzaville, where he studied philosophy, and subsequently he continued his studies at Reims. Back in Congo-Brazzaville, he worked as a philosophy teacher.
Ngolo was included as one of the 75 members of the National Transitional Council (CNT), which served as a transitional legislature from 1998 to 2002, and was designated as First Secretary of the CNT. In the May–June 2002 parliamentary election, he was elected to the National Assembly as the PCT candidate in Ongogni constituency, winning the seat in the first round with 99.69% of the vote. After the election, he was chosen as First Secretary of the National Assembly on 10 August 2002. Ngolo was a delegate to the African Parliamentary Union's 27th conference, held at Algiers in November–December 2004; he headed Congo-Brazzaville's national group and was elected by the conference delegates as Rapporteur of the APU's Executive Bureau.
In the June–August 2007 parliamentary election, Jean-Claude Gakosso replaced Ngolo as the PCT candidate in Ongogni; although there were rumors of rivalry between the two, Gakosso and Ngollo appeared together when Gakosso announced his candidacy, and Ngolo instead stood as the PCT candidate in the Ouenzé I constituency of Brazzaville. Ngolo won the Ouenzé I seat in the first round with 54.30% of the vote, and he was subsequently re-elected as First Secretary of the National Assembly on 4 September 2007, receiving 122 votes from the 129 deputies who were present. He was additionally assigned responsibility for the National Assembly's relations with the African Parliamentary Union.
