Eco Eye is an Irish television series broadcast on RTÉ One. It is presented by Duncan Stewart and focuses on environmental issues. Stewart's daughter Tania also features on the show; she reports from across Ireland, asking people their views on Ireland's environmental future.

Eco Eye airs every Wednesday at 19:30, with the 2009 series being the sixth of its kind overall. The 2009 series also entered Northern Ireland for the very first time when it examined important cross border issues such as shared waters, transboundary waste problems and tourism in Northern Ireland.
