Richard of Conisburgh, 3rd Earl of Cambridge (c. 1375 – 5 August 1415) was the younger son of Edmund of Langley, 1st Duke of York and Isabella of Castile.

His paternal grandparents were Edward III, King of England and Philippa of Hainault. His maternal grandparents were Peter of Castile and María de Padilla. He was born at Conisburgh Castle in Yorkshire, and was confirmed in the Earldom of Cambridge, which had been resigned by his brother, in 1414.

Later years and death

Following Anne's death, Cambridge married Matilda Clifford, daughter of Thomas de Clifford, 6th Baron de Clifford (1363–1391), but they were probably married a very short time before he was discovered to be one of the fomenters of the Southampton Plot against King Henry V immediately prior to departure on the French campaign. (His elder brother, Edward of Norwich, 2nd Duke of York, would die at the Battle of Agincourt, less than three months later.) He was stripped of all his titles and estates and was beheaded on 5 August 1415 at Southampton Green, Hampshire along with fellow conspirator Henry Scrope, 3rd Baron Scrope of Masham; the fleet set sail for France a few days later on 11 August 1415.

In 1461, following the Wars of the Roses, the House of York took the throne from the House of Lancaster and Cambridge's conviction and execution was annulled at the new king's first parliament, according to historian T B Pugh, as "irregular and unlawful".
