The 18th SS Mountain Police Regiment (German: SS-Polizei-Gebirgsjäger-Regiment 18) was initially named the 18th Mountain Police Regiment (Polizei-Gebirgsjäger-Regiment 18) when it was formed in 1942 from existing Order Police (Ordnungspolizei) units for security duties in Occupied Europe. It was redesignated as an SS unit in early 1943.
