The Royal Westphalian Railway (German: Königlich-Westfälische Eisenbahn, KWE) was a German rail company established in 1848 with funding from the Prussian government, which later became part of the Prussian State Railways. The network eventually extended about 315 km from Rheine via Hamm to Warburg and from Welver (near Hamm) to Oberhausen.
