Newport (Baile Uí Fhiacháin in Irish) is a small town in County Mayo, Republic of Ireland. It is located on the west coast of Ireland, along the shore of Clew Bay, north of Westport. The N59 road passes through the town. Castlebar is also near the town.

Newport has a very striking railway bridge (no longer used for rail carriage) like an aqueduct, which, with the catholic church on top of the hill, dominate the town and create a picturesque appearance.
