The 3rd SS Police Regiment (German: SS-Polizei-Regiment 3) was named the 3rd Police Regiment (Polizei-Regiment 3) when it was temporarily formed in 1939 from existing Order Police (Ordnungspolizei) units for security duties during the invasion of Poland.

It remained in the Netherlands for the rest of World War II.

The first incarnation of the 3rd Police Regiment was formed on 8 September 1939 in Katowice, Poland, from elements of Police Group 1 (Polizeigruppe 1) for security duties in the rear area of the 14th Army during the Polish Campaign.

[1] The regiment was ordered to be reformed in July 1942 in the Netherlands, but the regimental headquarters and the signal company were not formed until 2 September in The Hague.

In turn, the first battalion was redesignated as III./Police Regiment 5 at the beginning of 1943 and was replaced by the redesignation of the first battalion of Police Regiment 16 in February, then rebuilding in Tilsit, East Prussia (now Sovetsk, Kaliningrad Oblast).
