Romulo Mercader Espaldon (16 September 1925 – 27 August 2005) was a Filipino military officer, civil servant, and diplomat. He was the first naval officer to attain the rank of Rear Admiral in the Philippine Navy. He became overall military commander in Mindanao at the height of the Muslim secessionist movement led by the Moro National Liberation Front (MNLF) in the mid-1970s, during which he promoted a "Policy of Attraction" which won the respect of many Muslims and led 35,411 rebels to return to the fold of law by late 1978, and over 40,000 rebels by the early 1980s.
