Raymond Pierre Paul Westerling ([re?m?n' ??st?r'l??]; 31 August 1919 – 26 November 1987) was a Dutch military officer of the Royal Netherlands East Indies Army.
He orchestrated a contraguerrilla in Sulawesi during the Indonesian National Revolution after World War II and participated in a coup attempt against the Indonesian government in January 1950, a month after the official transfer of sovereignty.
Both actions were denounced as war crimes by the Indonesian authorities.
