"Islanders' Anti-China Coalition") or simply TLF (島抗) is an anti-communist secret society formed in Taiwan in 2016 and a resistance organization against the People's Republic of China (PRC), with membership of Taiwanese people, Hongkongers and South Mongolians.

[3] The predecessor of the TLF is the "Vanguard Party" (先鋒黨), an informal organization formed in Taiwan in 2014.

While outsiders do not know the total number of its members and the exact organizational structure, many mainland Chinese and Hong Kong media outlets estimate that there are TLF members in various parts of Taiwan and Hong Kong.
