Chin Lin or Kim Lin (Chinese: 金鄰/金邻; Thai: จินหลิน/กิมหลิน) was an ancient political entities in modern lower central Thailand exited from the 9 CE to the 3rd century.^[1]: 27

In the 3rd century CE, after defeating Tun Sun to control the trans-Kra Isthmus trade route and encircle Chin Lin,^{[1]: 20, 25 [2]: 258} king Fan Man of Funan attempted to seize Chin Lin,^[1]: 20 but failed due to his illness.^{[3]: 258 [2]: 269}

The location of Chin Lin remains unclear. It was first mentioned around 9 – 22 CE during the late Western Han period, a Chinese emperor Wang Mang sent an embassy to visit Chin-lin. Later in the 3rd century, Chin Lin was again mentioned in the account of Funan king Fan Shih-man's conquests in the Chinese text Liáng Shū, which states that Chin Lin was located 3,000 li north of the kingdoms of Ta-k'un (Ch'ü-tu-k'un) and Chü-li (Chiu-chih),^[2]: 258 speculated to be Kou-chih of Kole polis in present-day near Kuantan of Malaysia.^{[1]: 26–27} Palmer Briggs proposes that Chin-lin and its southern neighbor, Tun Sun, was the Mon countries. The boundary between this two entities was ill-defined, but probably not far above the present-Mergui-Tanintharyi Region.^[2]: 259
