Grigorios Orologas was a Greek Orthodox metropolitan bishop who served in northwest Anatolia during the early 20th century. Born in Manisa in 1864, he studied at the Theological School of Halki before beginning his clerical career. He held the position of Metropolitan of Strumica from 1902 until 1908, after which he was transferred to the Diocese of Kydonies. During the turbulent end of the Greco-Turkish War, he worked to protect his congregation, eventually facing execution by the Turkish Army in 1922.
