Nanyang Siang Pau or Nanyang Business Daily (simplified Chinese: 南洋商报; traditional Chinese: 南洋商報; pinyin: Nányáng Shāngbào) was founded by philanthropist-entrepreneur Tan Kah Kee on 6 September 1923 in Straits Settlements, currently published in Malaysia. Nanyang Siang Pau is one of the oldest Chinese-language newspapers in the country, with only Kwong Wah Yit Poh having been published longer. It has been published continuously except for four months in 1923 and 1924 and during the World War II between 1942 and 1945, before publication resumed on 8 September 1945.
