Aquilino Martin de la Llana Pimentel III (born January 20, 1964) commonly known as Koko Pimentel, is the son of the former senator Aquilino Pimentel, Jr. (1987–1992, 1998–2010) and Lourdes dela Llana-Pimentel. He was proclaimed on August 11, 2011 as the 12th winning senator in the 2007 election.
Pimentel holds a Bachelor of Science degree in Mathematics from Ateneo de Manila University and a Bachelor of Laws from University of the Philippines, Diliman. He was subsequently the topnotcher in the 1990 Philippine Bar Examinations.
Pimentel began working as a lawyer in 1990, and was commissioner (representing Mindanao) on the National Youth Commission from 1995–98. Since 2006 he has been a professorial lecturer from MBA-JD Consortium, De La Salle Professional Schools and Far Eastern University Institute of Law. He was conferred doctor of humanities honoris causa by the Polytechnic University of the Philippines(PUP) on May 18, 2012.
Running in only his second race in the May 14, 2007 senatorial elections, Pimentel was narrowly defeated by Bukidnon Congressman Miguel Zubiri for the 12th and last slot in the Philippine Senate. The narrow margin of 18,372 votes was hotly contested, particularly the votes from the southern Philippine province of Maguindanao, where Pimentel had lost heavily to Zubiri. 
Claiming the votes in Maguindanao were tainted, Pimentel petitioned the Supreme Court to issue a restraining order against the proclamation of Zubiri. With the vote tied at 7–7, the High Tribunal did not grant Pimentel's petition.
On July 14, 2007, Pimentel filed an electoral protest to the Senate Electoral Tribunal (SET). After finding grounds for a recount, the SET proceeded with the protest. On August 11, 2011, Pimentel won the protest and was proclaimed the rightful winner after Zubiri's resignation.
Pimentel was included in the United Nationalist Alliance's shortlist of candidates for the upcoming 2013 election, but his longtime foe Migz Zubiri was also included on the senatorial list of UNA. Instead of running with Zubiri, he ran under the administration coalition of the Liberal Party. Pimentel won during the elections, placing eighth.
