Chi Chia-wei (Chinese: 祁家威; born 2 August 1958) is a Taiwanese gay rights activist.

[1] In March 1986, Chi became the first person in Taiwan to come out as gay on national television, organizing a press conference to announce both his sexuality and his launch of a campaign to prevent the spread of AIDS/HIV.

He was detained at the Tucheng Detention Center and was kept in a room with 4 other political prisoners including further president Chen Shui-bian.

[4] After the Ministry of Justice ruled that marriage was only allowed for opposite-sex couples in 1994, Chi attempted to obtain a license again in 1998, eventually appealing the case in October 2000 to the Council of Grand Justice to offer a justification for their refusal to grant him a marriage license.

In the Taiwanese film Your Name Engraved Herein, the director pays homage to Chi, a character based upon him can be seen wearing the famous costume partly made of condoms and holding a sign stating "homosexuality is not a disease".
