Dimitrios Konstantopoulos, Greek footballer
Dimitrios Konstantopoulos (Greek: Δημήτριος Κωνσταντόπουλος; born 29 November 1978) is a retired Greek professional footballer who plays as a goalkeeper. He is currently the goalkeeping coach for EFL League Two side Hartlepool United.

After playing amateur football with Iraklis Ampelokipi, Konstantopoulos signed his first professional contract with Kalamata in 1996; he would go on to make 12 appearances in six years for the club, with a spell at Egaleo yielding three further appearances between 2001 and 2002. He moved to Portuguese side Farense after this, before joining Hartlepool United in October 2003. After making 117 league appearances for Hartlepool, Konstantopoulos opted to switch to Coventry City in 2007. However, he was unable to hold down a first team place, and, after loan spells with Nottingham Forest, Swansea City (twice) and Cardiff City between 2008 and 2009, Konstantopoulos was released in 2010 having made 31 league appearances for Coventry. He returned to Greece, spending a successful season with Kerkyra before switching to AEK Athens for the next two seasons. Following AEK's relegation, he was released at the end of his contract, and joined Middlesbrough in August 2013.

Internationally, Konstantopoulos made nine appearances for the Greek under-21 side, and made his full international début for Greece in 2011; this remains his only senior cap.
