Porsgrunn Station (Norwegian: Porsgrunn stasjon) is a railway station serving Porsgrunn, Norway. It serves regional trains on Vestfold Line and local trains on Bratsberg Line, all operated by the Norwegian State Railways. The station was built as part of Vestfold Line, then known as the Jarlsberg Line, and opened on 24 November 1882. In 1917, it became a station along the Bratsberg Line. The original station building was drawn by Balthazar Lange, and inspired by the concurrent style on the Østfold Line. The current station building, in red brick, was built in the 1960s.
