Cerasa, identifiable with Eliesler in modern Turkey, is an ancient episcopal see of the Roman province of Lydia in the civil Diocese of Asia. It was part of the Patriarchate of Constantinople and was suffragan of the Archdiocese of Sardis.

The lists of participants in the ecumenical councils have handed the names of four bishops of this ancient episcopal:

• Menecrates the Council of Chalcedon,
• John the Second Council of Constantinople,
• Michael the Second Council of Nicaea and
• Agathon at the Council of Constantinople dell'879- 880 that reinstated Patriarch Photios I of Constantinople.

Cerasa survives today as titular bishop but has been vacant since May 2, 2001.
