In Irish mythology Sláinge (Sláine, Slangia) was the name of two early settlers of Ireland.
1. Sláinge was a son of Partholón, who led the first settlement of Ireland after the Flood. Partholon's people arrived in 2680 BC or 2061 BC depending on which chronology is used, and may represent Neolithic farmers.
2. Sláinge son of Dela was a leader of the Fir Bolg, a later wave of settlers, and was the first Ard Ri or High King of Ireland. He reportedly came ashore at Wexford Harbour at the mouth of the River Slaney. He ruled only one year. He died at Dind Ríg in County Carlow and was buried at Slane, County Meath. He was succeeded by his brother Rudraige (2).
