Nicolae Constantin (born 9 December 1973 in Bucuresti) is a retired Romanian footballer.
He spent most of his playing career with his childhood club, Petrolul Ploiesti, and also at FC Rapid Bucuresti.
He played mainly as a central defender, but could also go as a center forward.
Although uncapped by Romania, he has been regarded as one of the best Romanian central defenders of his generation, since he was a very determined and hard-working man.
Nae Constantin retired at the end of the 2010-2011 season, last playing for second tier club Chimia Brazi.
