Lim Boon Heng (Chinese: 林文兴; pinyin: Lín Wénxīng; born 18 November 1947) is a Singaporean trade unionist and former politician.

In 1967, Lim was awarded a Colombo Plan Scholarship to study naval architecture at the University of Newcastle-upon-Tyne.

In 1971, he was awarded a one-year NORAD (Norwegian) Fellowship for practical training in Oslo, leading to a diploma in international shipping inspection.

Lim was approached by former NOL colleague Goh Chok Tong to contest in the 1980 general election.

Upon his return to the NTUC, he was elected Secretary-General and served for another four terms until he stepped down in December 2006 to make way for Lim Swee Say.

[citation needed] Lim was able to persuade union leaders to support the Central Provident Fund (CPF) cuts and reform during the 1998 recession.

He also rallied union leaders and workers to support the restructuring of key companies like PSA International and Singapore Airlines (SIA).

[citation needed] Aware of the many criticisms of his wearing the two hats - that of NTUC chief and Minister in the Cabinet, Lim argued that this arrangement gave labour a place to influence public policy-making at the highest level.

[citation needed] In August 1996, Lim was conferred the honorary Doctor of Business from the Royal Melbourne Institute of Technology for his role in developing and fostering tripartite relationship among government, employers and workers in Singapore.

In November 1996, Lim received the honorary Doctorate of Civil Law from his alma mater, the University of Newcastle Upon Tyne for his "combined academic distinction, business acumen, political commitment and social concern".

In 2007, the NTUC honoured Lim with the Distinguished Comrade of Labour for his contributions to the trade union movement.

The NTUC recognises Lim as having played a key role in building trust among tripartite partners in the tumultuous 1990s when Singapore was rocked by recessions, job losses, and economic restructuring.
