Poolbeg Chimneys are two large chimneys located in Dublin, Ireland. They were built in the 1970s as part of the Poolbeg Incinerator, a waste-to-energy power plant.

The chimneys are approximately 250 meters tall and are a prominent feature of the Dublin skyline.They are also known as “The Poolbeg Stacks” and are considered a local landmark. The plant was closed in 2010, but the chimneys still stand.
