Hong Kong Marriage Equality is a non-profit advocacy group, co-founded by Jerome Yau and Gigi Chao in 2019, based in Hong Kong. Its primary mission is to advance fair treatment for same-sex couples, eliminate discrimination, and promote LGBT+ equality within the region. The organisation actively campaigns for full marriage equality, engaging the public and criticising government proposals for same-sex partnerships that it deems too conservative or vague. It plays a significant role in advocating for comprehensive legal recognition and equal rights for same-sex relationships in Hong Kong.
