Middletown is a small village and townland in County Armagh, Northern Ireland.

At the bottom of the valleys that many of these drumlins form, glens can be found with many tributaries of the River Blackwater flowing through them.

[citation needed] Middletown was one of several Catholic border villages in Armagh that would have been transferred to the Irish Free State had the recommendations of the Irish Boundary Commission been enacted in 1925.

Middletown has a long history of Gaelic games and the local Gaelic Athletic Association club, Middletown GAA, plays hurling as Na Fianna, football as Eoghan Ruadh, and camogie as St John's.
