The United Daily News (Chinese: 聯合日報; pinyin: Liánhé Rìbào; Pe̍h-ōe-jī: Liân-ha̍p Li̍t-pò) is a daily broadsheet newspaper in the Philippines written in the Chinese language.

[2] The newspaper, the only Chinese-language newspaper that was authorized to publish during the martial law era,[3] was founded in 1973 by Cheng Kim Tiao,[4] merging two pre-existing Chinese-language newspapers: the Kong Li Po (公理報), founded in 1911, and the Great China Press (大中華日報), established after World War II.

[5] Both newspapers were known to be sympathetic to the Kuomintang, with the Kong Li Po even being founded by Wu Ching-ming, Sun Yat-sen's organizer in the Philippines.

[6] Its founding editor-in-chief, Sy Yinchow (Chinese: 施穎洲; pinyin: Shī Yǐngzhōu; Pe̍h-ōe-jī: Si Éng-chiu),[7] was the world's longest-serving editor-in-chief, having served in that position at a number of publications since 1945.

[8] Known as the "dean of Chinese media practitioners",[8] Sy wrote daily for the newspaper until his death in 2014.
