Kevin Tsai (Chinese: 蔡康永; pinyin: Cài Kāngyǒng; Pe̍h-ōe-jī: Chhòa Khong-éng; born 1 March 1962) is a Taiwanese television host and writer.

He is known for co-hosting the Chung T'ien Television talk show Kangsi Coming (2004–2016) with Dee Hsu and for his self-help book series Ways of Speaking.

In 1996, Tsai had his career breakthrough as he became the creative director of Voice of Taipei radio station,[2] the first editor-in-chief of GQ Taiwan and the host of his first TV show, Fanshu Chudian Wang, all in the same year.

Since 2004, Tsai and Dee Hsu co-hosted the talk show Kangsi Coming, which gained enormous popularity across the Chinese-speaking world.

However, the producer, James Chan, negotiated with the TV station to create a full season, which exceeded the hosting duo's original plan and ultimately fell through.
