The Ombudsman against Discrimination on Grounds of Sexual Orientation (Swedish: Ombudsmannen mot diskriminering på grund av sexuell läggning), abbreviated HomO, was the Swedish office of the ombudsman against discrimination on grounds of sexual orientation.
HomO was the most recently instituted Swedish ombudsman, in the sense of a government official who addresses the complaints of individual citizens.
The term HomO is used both to refer to the office and as the title of its government-appointed acting head.
HomO was the officially mandated short form, but is not a true acronym or abbreviation.
Instead the word alludes to both "homo" (homosexual) and to traditional Swedish ombudsman abbreviations which do expand into descriptive terms, such as JämO = Jämställdhetsombudsmannen.
