Nicolae "Nae" Constantin (born 9 December 1973 in Filipeștii de Târg) is a retired Romanian footballer . He spent most of his playing career with his childhood club, Petrolul Ploiești, 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.
