模擬聯合國(Model United Nations, MUN)又稱模聯，是一種學生模擬聯合國開會情形的活動。開會時，學生將扮演各國代表，遵循國際會議的議事規則並針對全球議題進行討論。
歷史上最早出現的模聯雛形是1927年由美國哈佛 (Harvard) 大學舉辦的模擬國際聯盟。1946年，第二次世界大戰結束，國際聯盟被聯合國取代，於是模擬國際聯盟被更改為模聯。

Model United Nations (Model UN, MUN) is an international activity which students participate in as delegates and simulate the committees of the United Nations. Participants have to follow the Rules of Procedure (ROP) in the conference and discuss global issues.
Delegates have to give speeches to elaborate the positions of the countries which they are representing based on the policies of the countries. Also delegates have to exchange their opinions with others through debating and lobbying, then delegates would write draft resolutions (DR). At last, delegates would vote on the draft resolutions and pass one of them.
The main purpose of MUN is to give students opportunities to understand the international situations nowadays, making students view global issues at objective positions, promoting the interchange of students from all over the world, and broaden the horizons of the students.
MUN activities are widespread among students from all over the world. There are a host of international MUN conference around the world, and there are myriads of local conferences each year.

The predecessor of MUN was the Model League of Nations, and the first recorded Model League of Nations activity was held by Harvard University. In 1946, after the Second World War, the League of Nations was dissolved and the United Nations was established. The next year, Model League of Nations changed into MUN.

In 1956, Frederick Chien(錢復), the former Minister of Foreign Affair, held the first MUN conference in Taiwan when he was at school. In 1999, the first MUN society in Taiwan, National Taiwan University Model United Nations (NTUMUN) was founded, and numerous MUN activities have been held in Taiwan since then. In 2007, NTUMUN organized the first annual session of High School Model United Nations camp, offering high school students an opportunity to participate in MUN activities. In 2011, Taipei Municipal ChengGong Senior High School Model United Nations Club was founded, becoming the first public school MUN society in Taipei city. In recent years, MUN clubs began more and more popular among high schools in Taiwan, and we hope we could lead the way and make progress in the future!
