Formosa Magazine, also known as Mei-li-tao, was a magazine created by Tangwai individuals in Taiwan during the summer of 1979. It opposed the Kuomintang's political monopoly in the Republic of China government. A police raid of the Formosa Press caused the Kaohsiung Incident in December 1979.

The Tangwai movement, or simply Tangwai, was a loosely knit political movement in Taiwan in the mid-1970s and early 1980s. Although the ruling Kuomintang (KMT) had allowed contested elections for a small number of seats in the Legislative Yuan, opposition parties were still forbidden. As a result, many opponents of the KMT, officially classified as independents, ran and were elected as members "outside the party." The movement was at times tolerated and other times suppressed, the latter being the case particularly after the Kaohsiung Incident of 1979. Members of the movement eventually formed the Democratic Progressive Party, which after opposition political parties were legalized, contested elections and won the Presidency with candidate Chen Shui-bian, ending decades of single party rule in Taiwan.
