John de Graham (died 1337)

Sir John de Graham of Dalkeith, Abercorn & Eskdale (1278–1337) was a 13th-14th century Scottish noble.

John, born in 1278, was the son of Nicholas de Graham of Dalkeith and Abercorn and Mary de Strathearn.

He fought at the Battle of Bannockburn against the English on 23–24 June 1314 and as a result had his Northumberland estates confiscated.
