Sliba-zkha (the name means 'the cross has conquered' in Syriac) was patriarch of theChurch of the East from 714 to 728.

Brief accounts of Sliba-zkha's patriarchate are given in theEcclesiastical Chronicle of the Jacobite writerBar Hebraeus (floruit 1280) and in the ecclesiastical histories of the Nestorian writersMari ibn Suleiman (twelfth-century),ʿAmr (fourteenth-century) andSliba (fourteenth-century). He is also mentioned in an unfavourable anecdote inThomas of Marga'sBook of Governors.

The following account of Sliba-zkha's patriarchate is given by Bar Hebraeus:

The catholicusHnanishoʿ was succeeded by Sliba-zkha, who was consecrated at Seleucia. He was from Karka d'Piroz, which is today called Karkani, in theTirhan region. He removed the name ofYohannan Garba ('the Leper') from the diptychs, reconsecrated the bishops consecrated by Garba, and put back the name ofHnanishoʿ, who had been oppressed by calumny, alongside those of the rest of the catholici. He died after fulfilling his office for fourteen years.^[1]

According to ʿAbdishoʿ of Nisibis, Sliba-zkha established metropolitan provinces for Herat, Samarqand, India and China.^[2]
