John Foster of Dunleer

John Foster of Dunleer (born 1665-died 16 May 1747) was elected member to the Irish House of Commons for the constituency of Dunleer, in County Louth. He formerly held the position of Mayor of Dunleer Corporation.

He was the son of Colonel Anthony Foster of Dunleer, whose father Samuel had come to Ireland from Cumberland. He married in 1704 Elizabeth Fortescue, youngest daughter of William Fortescue of Newrath, County Louth, and first cousin to William Henry Fortescue, 1st Earl of Clermont. They had six children:
 * Anthony Foster, Chief Baron of the Irish Exchequer
 * Rev Thomas Foster DD

 * Margaret Foster who married Stephen Sibthorpe
 * Charlotte Foster who married Nicholas Forster
 * Alice Foster who married Thomas Bolton.
 * Rhoda Foster who married Roger Anketell
