Seda Sayan (born Aysel Gürsaçer; 30 December 1962) is a Turkish pop folk singer, actress, and TV variety-show hostess.

Sayan was born in a poor family so she started working from a very young age. She started performing at the age of 16. She had her date of birth changed via a court decision in 1978 to 4 January 1959, in order to be eligible for performing at a specific venue. In December 2017, she changed her date of birth back to 1962. Her big shot came in 1984 when she played a role in a movie opposite Kadir İnanır.
