D'Olier Street /dəˈlɪər/ is a street in the southern city-centre of Dublin, the capital of Ireland. It and Westmoreland Street are two broad streets whose northern ends meet at the southern end of O'Connell Bridge over the River Liffey. Its southern end meets Fleet Street, Townsend Street, College Street and Pearse Street.
The street is named after Jeremiah D'Olier (1745–1817), a Huguenot goldsmith and a founder of the Bank of Ireland. D'Olier was the City Sheriff in 1788 and a member of the Wide Streets Commission. The street was one of the last major interventions in the Dublin city plan to be executed by the Wide Streets Commissioners.
From 1895–2006, Irish Times was based in D'Olier Street, leading the paper to be nicknamed The Old Lady of D'Olier Street. The paper is now based in Tara Street.
In 1830, Samuel Lover was secretary of the Royal Hibernian Academy and lived at number 9 D'Olier Street.
In 1891 James Franklin Fuller designed the D'Olier Chambers building of yellow brick and terracotta for the Gallaher Tobacco Company.
