Sir Richard Morrison (1767 – 31 October 1849 / 1844) was an Irish architect.
He was born at Midleton, County Cork, the son of John Morrison, also an architect. Originally intended for the church, he was eventually placed as pupil with James Gandon, the architect, in Dublin. He obtained through his godfather, the Earl of Shannon, a post in the ordnance department at Dublin, but this he abandoned, when he entered into full practice as an architect.
Having resided for some time at Clonmel, where his son, William Vitruvius was born, he moved about 1800 to Dublin and settled at Bray, County Wicklow.
He died at Bray on 31 October 1849, and was buried in Mount Jerome Cemetery, Dublin. Other sources claim his death in 1844.
He was a founder-member in 1839 and first vice-president of the Royal Institute of the Architects of Ireland. In 1793 he published Useful and Ornamental Designs in Architecture.
Morrison designed a number of works with his son, William Vitruvius Morrison, including: Baronscourt, near Newtownstewart in County Tyrone (from 1835); Kilruddery House, near Bray in County Wicklow; Ballyfin, just north of Mountrath in County Laois; and Fota, near Cork in County Cork. Richard Morrison also designed Knockdrin Castle, just north of Mullingar in County Westmeath.
