Lo Ta-yu (Chinese: 羅大佑; pinyin: Luó Dàyòu; born 20 July 1954), also known as Luo Dayou and Law Tai-yau, is a Taiwanese singer and songwriter.

What captured the hearts of a generation, however, were his lyrics, touching on issues of life, attitudes, social responsibility, and the political problems of both Chinese Mainland and Taiwan with an underhandedly critical strain of dark humor.

[4] Lo debuted in the music industry in 1977, composing part of the soundtrack of the film Golden Days (閃亮的日子) and writing songs for his partner Sylvia Chang's album Childhood (童年).

[6]: 166  He also wrote "Queen's Road East" (皇后大道東), a 1991 Cantonese song he sang with Ram Chiang that satirizes the impending Hong Kong handover in 1997.

In 2004, Lo formally relinquished his US citizenship to protest the introduction of a resolution to the US House of Representatives requesting the deployment of Taiwanese marines to Iraq.

[8] On Sunday, 25 May 2008, at 7 pm PST, Lo held a live concert at San Jose State University Event Center.
