The alarm was raised shortly after 5.30 a.m. this morning by a man from a neighbouring house who discovered the fire.
The Enniscorthy Fire Brigade arrived a short time later at the two-storey house (photo).
The bodies of the parents and the two children were found inside and remain at the scene for the time being.
Post mortem examinations will be carried out later today and Gardaí have begun an investigation into the cause of the fire.
