Pernis (Dutch pronunciation: [pɛrˈnɪs]) is a neighborhood and submunicipality (since 3 March 2010) of Rotterdam, Netherlands. The district has a population of 4,845 (2018) on a total area size of 1.60 km (0.62 sq mi). Pernis is thus a full submunicipality of Rotterdam, but the former independent municipality had its own district council already. Although surrounded by ports, Pernis has preserved its village-like atmosphere very well.
Pernis is best known for its petrochemical industry. Refineries define its skyline. Shell's sprawling complex located there is the largest oil refinery in Europe, and one of the largest in the world.
