David Plunket, 1st Baron Rathmore

David Robert Plunket, 1st Baron Rathmore (December 3, 1838) - (August 22, 1919) was an Irish politician. The third son of John Plunket, 3rd Baron Plunket, and brother to the 4th Baron, he was educated at Trinity College Dublin and was called to the Irish bar in 1862. After practising on the Munster Circuit for a number of years, he was made a Queen's Counsel in 1868, and became legal adviser to Dublin Castle that same year.

In 1870, Plunket was elected Conservative Member of Parliament for Dublin University, and was Solicitor General for Ireland from 1875 to 1877. He was then briefly Paymaster General in 1880, and in 1885 he became First Commissioner of Works in Lord Salisbury's first ministry, resuming office after a short interval when the Conservatives returned to power the following year. He sat in the Cabinet until 1892, and on his retirement in 1895 he was created Baron Rathmore, of Shanganagh in County Dublin.

A director of the Suez Canal Company as well as Chairman of the North London Railway for many years, Lord Rathmore died, unmarried, at the age of 80 in a hotel in Greenore, County Louth. His peerage became extinct at his death.
