The THIMUN Singapore conference is a five-day simulation of the United Nations for secondary school students, which takes place in the second half of November each year in Singapore. THIMUN Singapore was established in 2004 as a sister conference to THIMUN(The Hague Model United Nations) and is a part of the THIMUN Foundation. It has taken place since the very first conference in the prestigious Hwa Chong Institution, and students and staff from the school have supported the conference in many different roles. As well as the full range of committees, including the Human Rights Council and ECOSOC, the conference has its own newspaper, Munity East.
The next physical THIMUN Singapore conference will take place in November 2022 at the Hwa Chong Institution, Singapore.
