Kemalettin Şentürk (born 9 February 1970) is a Turkish retired footballer who played mainly as a sweeper but also as a defensive midfielder, and a manager.
Born in Artvin, Şentürk started his professional career with Çaykur Rizespor in the second division, signing for Gençlerbirliği S.K.
Always an important first-team element, Şentürk contributed with 24 matches and three goals in the 1995–96 campaign as Fenerbahçe lifted the national championship, scoring in a 3–1 home win against runners-up Trabzonspor on 9 December 1995.
Leaving Fenerbahçe in June 2000, Şentürk joined Diyarbakırspor, then made a brief top flight return with Antalyaspor and retired for good in late 2005, after having played for modest clubs: Kahramanmaraşspor, Osmaniyespor, Kütahyaspor, Mustafakemalpaşa Spor and MKE Kırıkkalespor.
Şentürk played five times for Turkey during slightly more than one year, making his debut on 30 August 1995 in a 2–1 friendly home win over Macedonia.
