John Kourkouas or Curcuas (Greek: Ἰωάννης Κουρκούας) was the Byzantine catepan of Italy from 1008 to 1010.
[1] According to a deed of grant to the monastery of San Giovanni in Lamis, he bore the titles of anthypatos and patrikios.
[2] Kourkouas arrived at Bari in May 1008,[2] as a replacement for Alexios Xiphias,[1] who had died sometime between April and August of the previous year.
[3] He served as catepan of Italy until some time before March 1010, when his successor, Basil Mesardonites, is attested in office.
[1] A possible descendant or relative, the notary John Kourkouas, is attested in southern Italy some time before 1054.
