The Organisation of Lesbian and Gay Activists (OLGA) was an LGBT rights organisation in South Africa. The group started as Lesbians and Gays Against Oppression (LAGO) and in 1987 reorganised as OLGA. Both organisations fought for LGBT rights and were anti-apartheid. OLGA was affiliated with the United Democratic Front (UDF) and sent suggestions for a more inclusive constitution for South Africa to the African National Congress (ANC).
