"Mystiko" (; "Secret") is a single by the Greek singer Peggy Zina. It was released on July 9, 2007 by Minos EMI. It has also been repackaged with Zina's album Ena and sold as Ena New Edition.
The song "Mystiko" was written for her wedding, where she sang the song to her husband at the reception.
Mystiko (foaled 1988) was an American-bred, British-trained Thoroughbred racehorse and sire. In a career that lasted from July 1990 to October 1992 he ran thirteen times and won four races, all of them at Newmarket. After taking the European Free Handicap on his first appearance as a three-year-old he recorded his most important success when winning the 2000 Guineas seventeen days later. His subsequent form was disappointing, although he did win the Challenge Stakes that autumn. In 1993 he was retired to stud, but had little success.
