Number 1 (Chinese: 男儿王; pinyin: Nán'érwáng; lit. 'King of [True] Men') is a 2020 Singaporean comedy-drama film written by Jaspers Lai and directed by Ong Kuo Sin. The film stars Mark Lee, Jaspers Lai, Kiwebaby Chang, Kenneth Chia, Darius Tan and Henry Thia. The film revolves around an out-of-work middle-aged man who accidentally becomes a night club drag queen sensation. Mark Lee, Henry Thia and Gadrick Chin would later collaborate again in the future local celebrity and successful film director Jack Neo durian movie known as The King of Musang King, in which Lee also portrayed a very similar role just like this film where both roles featured his characters looking for many jobs and work on them but ultimately were all failed attempts, which led them working as a durian seller with his family in that film and drag queen in this film respectively.

The film was released on 22 October 2020 in Singapore and released on 10 February 2021 in Taiwan. It received two nominations at the 57th Golden Horse Awards, including Best Leading Actor for Mark Lee, and won Best Makeup and Costume Design.
