Henry I of Cyprus, nicknamed the Fat, aka Henry of Lusignan or Henri I le Gros de Lusignan (May 3, 1217 – January 18, 1253 at Nicosia) is King of Cyprus from 1218 to 1253.

He is the son of Hugh I of Cyprus and Alice of Champagne of Jerusalem.

When his father Hugh I dies on January 10, 1218, the 8-month-old Henry becomes king.

His mother is the official Regent, but hands off the actual governing to her uncle, Philip of Ibelin.

When Philip dies, the effective regency passes to his brother, John of Ibelin, the Old Lord of Beirut.
