A candareen (/kændəˈriːn/;^[1] Chinese: 分; pinyin: fēn; Cantonese Yale: fàn;^[2] Singapore English usage: hoon^[3]) is a traditional measurement of weight in East Asia. It is equal to 10 cash and is 1⁄10 of a mace. It is approximately 378 milligrams. A troy candareen is approximately 374 milligrams (5.77 gr).

In Hong Kong, one candareen is 0.3779936375 grams^[2] and, in the Weights and Measures Ordinance, it is 2⁄150 ounces avoirdupois. In Singapore, one candareen is 0.377994 grams.^[3]

The word candareen comes from the Malay kandūri.^[1] An earlier English form of the name was condrin.^[1] The candareen was also formerly used to describe a unit of currency in imperial China equal to 10 li (釐) and is 1⁄10 of a mace. The Mandarin Chinese word fēn is used to denote 1⁄100 of a Chinese renminbi yuan but the term candareen for that currency is now obsolete.

On 1 May 1878 the Imperial Maritime Customs was opened to the public and China's first postage stamps, the "Large Dragons" (Chinese: 大龍郵票; pinyin: dài lóng yóupiào), were issued to handle payment. The stamps were inscribed "CHINA" in both Latin and Chinese characters, and denominated in candareens.^[4]
