John McKean (6 January 1869 – 14 May 1942) was an Irish nationalist politician and Member of Parliament (MP) in the House of Commons of the United Kingdom of Great Britain and Ireland.
He was first elected unopposed as the Irish Parliamentary Party (IPP) MP for the South Monaghan constituency at the 1902 South Monaghan by-election, caused by the resignation of James Daly.
From 1909, having left the IPP, he sat as an Independent Nationalist MP.
His brother James J. MacKean was a member of Seanad Éireann from 1922 to 1936.
