Süreyya Ayhan Kop (born September 6, 1978) is a Turkish former female middle distance track runner who specialised in the 1500 metres.

Born in Korgun, Çankırı, she established herself as Turkey's top 1500 m runner with a win at the 1999 national championships, setting a Turkish record.

[citation needed] In 2002, she won Turkey's first gold medal in a European Championships by out-sprinting World and Olympics champion Gabriela Szabo from Romania for the 1500 m title 2 seconds ahead with 3:58.79, leading from the gun to the finish.

[citation needed] Ayhan, one of Turkey's best hopes for a gold medal at the 2004 Athens Olympics, withdrew from the games due to an injured tendon during a training in Germany.

Allegations that Ayhan may have attempted to cheat on a pre-Olympic doping test surfaced in August after testers reportedly complained of being obstructed from carrying out their work.
