Richard Joshua Cooper (18 July 1860 – 13 May 1938) was an Irish-born army officer and local politician.
He was the second son of Colonel Rt. Hon. Edward Henry Cooper (1827-1902), an officer in the Grenadier Guards and member of parliament for Sligo and his wife Charlotte Maria nee Mills.
Cooper was commissioned into the Coldstream Guards in 1880, fighting in the Anglo-Egyptian War of 1882. When the Irish Guards were formed in 1900, Cooper transferred to the new regiment. By the time of the outbreak of the First World War in 1914 he had reached the rank of colonel. He was promoted to Brigadier-General, commanding the 29th Infantry Brigade during the Gallipoli Campaign.
He married Constance Mary Grant-Thorold in 1904. The couple had no children.
He was elected to the London County Council at a by-election on 13 May 1912 as a Municipal Reform Party councillor representing Islington North. He was re-elected at the council elections in March 1913. Elections were suspended for the duration of the First World War. When elections resumed in 1919 new electoral boundaries were used: Cooper was elected as a councillor for Westminster St George's. He held the seat three years layer and stood down from the county council at the 1925 election.
