Irishtown Nature Park, Dublin, Nature park in Poolbeg Peninsula, Dublin, Ireland

Irishtown Nature Park is a green space on the Poolbeg Peninsula in Dublin, created from an industrial site that locals transformed into a nature area. The park contains meadows and vegetation zones with walking paths that lead through open land toward the water's edge.

Irishtown Nature Park was devised during a building boom in the 1970s, when rubble and waste were dumped on the site between Irishtown and Sandymount Strand. The Sandymount and Merrion Residents Association proposed turning the dump into a nature reserve, and in the 1980s Dublin Corporation worked with local residents to plant seeds, trees and tall grasses. In the early 1980s, up to 30 lorry loads of archaeological rubble from the Wood Quay excavation were dumped at the park's original location.

The park's name in Irish is Páirc Dhúlra an Bhaile Ghaelaigh, linking it to the old Irishtown district beside Sandymount Strand. It was the Sandymount and Merrion Residents Association that proposed turning the dump into a nature reserve, and local residents helped Dublin Corporation plant seeds, trees and tall grasses in the 1980s. Birdwatchers come each year for skylarks, linnets, stonechats and Brent geese.

Two entrances serve the park: an off-road path on Beach Road, opposite Marine Drive, runs 1.4 km along the edge of Sandymount Strand to the park gate, and a second entrance is on Pigeon House Road near the Poolbeg Generating Station. Several kilometres of walking trails cross the peninsula.

The park's plant list includes a pyramidal orchid and a rare beetle, Oedemera lurida, alongside two non-native species, sycamore and Japanese knotweed. Birdwatchers record skylarks, linnets, stonechats and Brent geese here each year.
