Poulaphouca, officially Pollaphuca (),Placenames Database of Ireland is the name of a waterfall and bridge on the River Liffey between County Wicklow and County Kildare. It is primarily known for its hydroelectric generating station and the associated artificial lake, known as Poulaphouca Reservoir, Poulaphouca Lake, or Blessington Lakes. The once-famous Poulaphouca Waterfall has little water running over it any longer because of the hydroelectric project.

The waterfall, marked as 'Poolapooka - a remarkable cataract' on Noble & Keenan's map of 1752, is depicted and described in the Post-Chaise Companion of 1786, when Ballymore parish was still within Dublin:
