Rath (Irish: An Ráth, meaning 'the ringfort')[1] is a hamlet in the south west area of County Offaly, Ireland.

As the place-name suggests, Rath takes its name from the Irish word 'An Ráth' which means ringfort.

[1] Ringforts are circular fortified settlements with some dating as far back as the Iron Age (800 BCE–400 CE).

The O'Molloy clan were chieftains of the territory and had a castle in nearby Eglish (the remains of which are still visible today).

The remains of the old church and high cross date back to the early Christian Ireland.
