Desmond Lim Bak Chuan (Chinese: 林睦荃; pinyin: Lín Mùquán; born 1967)[citation needed] is a Singaporean politician.

[2] Formerly a principal engineer at telco company M1,[1] Lim made his electoral debut in the 2001 general election when he joined a five-member SDA team to contest in Jalan Besar GRC against a five-member team from the governing People's Action Party (PAP).

Widely seen in opposition circles as a friendly person who is pleasant to talk to, Lim is also known for his willingness to attempt new methods of campaigning and has described himself as "dedicated and determined".

[9] When he was campaigning during the 2013 by-election, he was ridiculed for his poor diction in the videos of his speeches he had posted online.

Lim contested as a solo SDA candidate for the first time in that general election in a three-cornered fight in Punggol East SMC.

[4] Due to having garnered lower than 12.5% of the vote, Lim forfeited his S$16,000 election deposit under Singapore's electoral rules.

Lim announced his decision to contest as a SDA candidate in the by-election, which turned out to be a four-cornered fight pitting Lim against three other candidates: Koh Poh Koon of the PAP; Lee Li Lian of the Workers' Party; and Kenneth Jeyaretnam of the Reform Party.

[12] Although he was derided for his poor diction, he said he was not disheartened and felt that he should not be judged on his command of English, but on how he could serve the people.
