Guy of Ibelin, seneschal of Cyprus

Guy of Ibelin (French: Guy d'Ibelin) (before 1306 or before 1307 – after 14 April 1350 or 1350/1360) was Seneschal of Cyprus from 1318 and a Burgher of Venice from 30 December 1334. He was the son of Philip of Ibelin (1253–1318), previous Seneschal of Cyprus and Jerusalem by his second wife Maria Embriaco of Giblet (d. 1331). He was evidently held in high regard by King Hugh IV of Cyprus, since he is named in a royal decree from 1329 as a "magnificus vir" , in charge of four newly created priesthoods in the cathedral of Nicosia.

He married with papal dispensation on 13 November 1319 Margaret of Ibelin (1307 - ?), sister of Alice of Ibelin and daughter of Guy of Ibelin and wife Isabella of Ibelin. They had three children: John (name uncertain) of Ibelin (d. after 1367), Seneschal of Cyprus in 1363 after his father's death Alice of Ibelin (d. after 1374), who married John of Lusignan (1329/30-1375), titular Prince of Antioch and Regent of Cyprus Margaret of Ibelin (1325-1330 - ?)
