Brigadier General Charles Compton William Cavendish, 3rd Baron Chesham KCB PC DL (13 December 1850 - 9 November 1907), styled The Honourable Charles Cavendish between 1863 and 1882, was a British soldier, courtier and Conservative politician. He served as the last Master of the Buckhounds under Lord Salisbury from 1900 to 1901.

He entered the Coldstream Guards in 1870. Three years later, he joined the 10th Royal Hussars as a captain, and 1878 joined the 16th Lancers. Chesham held an appointment as Lieutenant colonel of the Royal Buckinghamshire Hussars Yeomanry from 1889. In January 1900 he was appointed in command of the 10th battalion of the Imperial Yeomanry (which included companies from Buckinghamshire, Berkshire and Oxfordshire), serving in the Second Boer War, and received the temporary rank of Colonel in the Army.

Later that year, he was promoted to Brigadier General and in November 1900 appointed a Knight Commander of the Order of the Bath (KCB) for his services (he was invested by King Edward VII at Marlborough House on 25 July 1901 during a brief visit to London). From 1901 he was Inspector general of Imperial Yeomanry in South Africa, with the local rank of Major-General.
