Sir Griffin Markham (d. aft. 1644) was an English soldier, the son of Thomas Markham and Mary Griffin. On 29 May 1592, he married Anne Roos. He was knighted in 1594 after serving under the Earl of Essex at the siege of Rouen. During the Nine Years War he commanded the cavalry under Sir Conyers Clifford, and his opportune arrival and counter-charge after the defeat of the infantry at the Battle of Curlew Pass (1599) saved the army from complete disaster. His right arm was broken during the affray.
