Drogheda Grammar School is an Irish co-educational multi-denominational school, located on Mornington Road, Drogheda, County Louth.

Henry Singleton (1682–1759) was an Irish politician and judge, who is remembered now mainly for his friendship with Jonathan Swift, and for his notable acts of charity during the Great Irish Famine of 1740-1, in which between 300,000 and 500,000 people died. Singleton House, his impressive townhouse in Drogheda, no longer exists.
