Belgium officially recognizes same sex marriages.

Lesbian, gay, bisexual, transgender (LGBT) rights in Belgium have been seen as some of the most progressive in Europe and in the world. Same-sex sexual activity was legalized in 1795, with an equal age of consent, except from 1965 until 1985. After granting same-sex couples domestic partnership benefits in 2000, Belgium became the second country in the world to legalize same-sex marriage in 2003. Same-sex adoption was completely legalized in 2006 and is equalized with that of opposite-sex adoption. Lesbian couples can get access to IVF as well. Discrimination protections based on sexual orientation in employment, housing, and public and private accommodations have also been enacted since 2003 and on gender identity/expression since 2014. Transsexuals have been allowed to change their legal gender under certain circumstances since 2007.

Belgium has frequently been officially referred to as one of the most gay friendly countries in the world, with recent polls indicating that a majority of Belgians support same-sex marriage and adoption. The previous Prime Minister of Belgium, Elio Di Rupo, is an openly gay man and was one of the only three Prime Ministers in the world to identify as LGBT. Pascal Smet, the former Flemish Minister of Education and current Brussels minister, is also openly gay.
