Nanyang Siang Pau (Chinese: 南洋商報; pinyin: Nányáng Shāngbào) as name Nanyang Sin Chew (Chinese: 南洋星洲; pinyin: Nányáng Xīngzhōu) was a newspaper in Singapore that was founded by philanthropist-entrepreneur Tan Kah Kee on 6 September 1923 in Singapore.
On 2 May 1971, three senior staff of the newspaper were arrested, accused of "a deliberate campaign to stir up Chinese racial emotions".
The newspaper merged with Sin Chew Jit Poh on 16 March 1983 to form the current Lianhe Zaobao and has ceased to exist.
A version of the newspaper is still in print in Malaysia.
