Cass Phang (Chinese: 彭羚; born 2 February 1969) is a retired Cantopop singer from Hong Kong, affiliated with EMI from 1993 to 1998 and then with Sony Music Entertainment.

In September 1998, she married Hong Kong actor and pop singer Jan Lamb, a member of musical rap duo DJ Softhard.

However, it was only with her second album, Love, Pain, I'm Still Waiting (愛過痛過亦願等) that she began to garner some success, when the title song was recognised in the Billboard Awards.

In 1993, Phang signed to EMI, releasing her fifth album, So Beautiful...To Be With You (有著你...多麼美), which included her first foray into more dance orientated tracks.

In 1994, she released her first compilation Unfinished Novel (未完的小說), which included the new single, Let Me Go With You (讓我跟你走), on which Eric Moo laid down vocals for.

The year 1995 proved to be a pivotal one in her career, with the release of several popular albums, Awakening From A Dream (如夢初醒), Fly With Love (隨愛而飛) and Outside the Window (窗外).

In October, she recorded her next Mandarin album, Passionate Love (好好愛), on which she sang a popular duet with Wang Lee-hom.

A dynamic shift in her career took place when Cass was cast in the role of Teresa Teng, in a musical celebrating the life of the late singing legend.

Originally scheduled to perform at the Hong Kong Arts Festival, she was replaced by fellow Sony solo artist, Candy Lo.
