Baak Maan Fu Yung (Chinese: 百萬富翁, Cantonese Yale: baak3 maan6 fu3 yung1, Jyutping: baak3 maan6 fu3 jung1, literally The Millionaire, also had the English words of Who Wants to Be a Millionaire surrounding the Chinese title) is a Hong Kong game show, based on the original British format of Who Wants to Be a Millionaire?.

The main goal of the game is to win HK$1 million (US$129,000) by correctly answering 15 multiple-choice questions.

Baak Maan Fu Yung first aired on April 29, 2001.

It is notable in ATV's 58-year history for being one of its few viewership successes over its rival station TVB.
