Belashtitsa Monastery, Orthodox monastery in Belashtitsa village, Bulgaria.

Belashtitsa Monastery is an Orthodox convent in the Western Rhodope Mountains, 12 km south of Plovdiv near Belashtitsa village. Its complex comprises a church, a chapel, dwellings and farm buildings. The church, built in 1838 on medieval remains, is single-nave and single-apse with an inner and outer narthex, no dome and no frescoes; a massive vaulted narthex was preserved. A stone fountain from 1831 stands in the yard.

Nikephoros Xiphias, Byzantine governor of Plovdiv from 1018, founded the monastery in 1020 and dedicated it to St George. Ottoman forces destroyed it in 1364; it was rebuilt in the 18th century, then burned again in 1878 during the Russo-Turkish War. After Bulgaria's Liberation it was restored but stayed under the Patriarchate of Constantinople until 1906.

The convent is dedicated to St George the Victorious, and its patronal feast is celebrated on 6 May, St George's Day (Gergyovden). The monastery belongs to the Plovdiv diocese of the Bulgarian Orthodox Church and only came under the Bulgarian Exarchate in 1906, after centuries under the Patriarchate of Constantinople.

The monastery sits south of Plovdiv and is accessible by road through the Rhodope region. As an active convent, visiting hours may vary depending on religious services, so checking conditions before arrival is wise.

The monastery was founded in 1020 by the Byzantine commander Nikephoros Xiphias, governor of Plovdiv from 1018. According to legend, Basil II gave him 15,000 captured soldiers of Samuel's army, and these prisoners founded the nearby village, later called Belashtitsa. Ruins of Xiphias's fortress-palace stand near a 1,000-year-old oriental plane tree south of the village.
