Lakis Nikolaou (Greek: Λάκης Νικολάου; born 17 July 1949) is a Greek former professional footballer who played as a centre back. He is the current medical director of AEK Athens.
 Nikolaou was born on July 18 of 1949 in Ios of Cyclades. He spent his school years in Peristeri and finished high school in 1966 at the Anargyrio and Korgialenio School, in Spetses where he was enrolled as a boarder together with his brother. He started playing football at an early age, when with friends and neighbors they formed the Irodotos Peristeri team, playing friendly matches with other teams in the area. In these matches he was watched by the people of Atromitos, who signed in 1967. In Atromitos he started playing as a defender and then as a striker, due to the team's lack of attackers. Finishing high school, he succeeded in entering the Mathematics Department but his burning desire to study medicine made him drop out of school and enroll in the Medical School of Bari, with the purpose of transferring to the University of Athens, which he did. During his stay in Bari, he played with the amateur team Barletta as a sweeper.
 In 1971, after 4 years of presence in the offensive line of Atromitos, he aroused the interest of the big clubs. In one of Atromitos' matches, the then coach of AEK Athens, Branko Stanković and the administrator of the club Stamatis Papastamatiou, who watched the match, were impressed by the playing style of Nikolaou. So AEK acquired Niklaou with a promise of 300 thousand drachmas as a signature premium, which was never given to him. For 3 years he competed as a striker, while at the same time he continued his studies at the Medical School. This juxtaposition proved particularly difficult as required attendance at faculty workshops and mandated attendance at team practiced often come at the expense of one another. This double occupation brought Nikolaou very close from being released from AEK in 1974, but under the possibility of signing to any of their big rivals, the president of AEK, Barlos called him to stay in the club. Nikolaou accepted with the term that the 1971 signature premium of 300 thousand drachmas to be given to him and rejoined the team but the pay remained to be seen until today. Under František Fadrhonc he was moved to the center of the defense, giving AEK a leader in defense for the next decade. The team of Barlos and Fadrhonc, where Nikolaou was a starter, excelled in Greece and abroad as they progressed to the UEFA Cup semi-final in 1977. winning 2 Championships and 1 Greek Cup including a double in 1978. The defensive partnership he created alongside Petros Ravousis, complementing each other were considered one of the best defensive duos in the history of the league. He was declared "Athlete of the year" for the years 1974 and 1979 by the Panhellenic Sports Press Association. After the departure of Mimis Papaioannou, Nikolaou became the team's captain for many years. In the summer of 1980, Nikolaou decided to stop his football career remaining in the club only as the team's doctor. As AEK faced problems midseason, Nikolaou was urgently called by the then coach, Miltos Papapostolou to put on his football shoes again and help the team. He accepted and competed for another one and a half season in the yellow-black jersey. His final match was on May 30, 1982 against Kastoria.
