Limahong, Lim Hong or also called Lin Feng (simplified Chinese: 林风; traditional Chinese: 林風; pinyin: Lín Fēng; Pe̍h-ōe-jī: Lîm-Hong) was a notorious Chinese pirate and warlord who invaded the northern Philippine Islands in 1574. He built up a reputation for his constant raids to ports in Guangdong, Fujian and southern China. He is noted to have twice attempted, and failed, to overthrow the Spanish city of Manila in 1574.

Born Dim Mhon to a poor family in the city of Tru Cheo (Teochew) in the province of Cuy Tan (called Catim by the Portuguese during the middle of the 16th century). Known to be called Limahong, he had an early start in criminal activity and progressed to piracy becoming leader of around 2000 pirates. His activities and attacks on ports and ships throughout southern China increased and a warrant was issued by the authorities to capture him alive and send him to the city of Tay Bin. He was married to Nataracy.

He shifted his activities to piracy on the high seas and out of reach of China's power. He was able to accumulate up to 40 ships, whereupon he once again raided cities and ports in southern China. Limahong attacked a city occupied by Vinh To Quiam, another pirate, but Vinh was able to escape along with 5 of Limahong's ships. However, Limahong was able to capture 55 of Vinh's fleet and thus increased his own to 95 ships. He was now a veritable king of the high seas of southern China.
