Lesbian, gay, bisexual, transgender, and queer (LGBTQ) people in the U.S. state of Hawaiʻi enjoy the same rights as non-LGBTQ people. Same-sex sexual activity has been legal since 1973; Hawaii being one of the first six states to legalize it. In 1993, a ruling by the Hawaiʻi Supreme Court made Hawaii the first state to consider legalizing same-sex marriage. Following the approval of the Hawaii Marriage Equality Act in November 2013, same-sex couples have been allowed to marry on the islands. Additionally, Hawaii law prohibits discrimination on the basis of both sexual orientation and gender identity, and the use of conversion therapy on minors has been banned since July 2018. Gay and lesbian couples enjoy the same rights, benefits and treatment as opposite-sex couples, including the right to marry and adopt.
Same-sex relationships have been part of Hawaiian culture for centuries. The term aikāne refers to homosexual or bisexual relationships, which were widely accepted in pre-colonial Hawaiian society, and the term māhū refers to a "third gender" alongside male and female. The Christian missionaries, who arrived in the 19th century, were adept in converting the local population to Christianity. As a result, the first ever anti-gay law was enacted in 1850, prohibiting sodomy with 20 years hard labor. During the 1960s and onwards, LGBTQ people entered into the public eye, which was followed by multiple pro-LGBT rights reforms, including the repeal of the sodomy law.
