Multidimensional discrimination, also called intersectional or multiple discrimination, refers to experiences of discrimination where several discrimination realities intersect with each other at the same time. Trans* people who experience multidimensional discrimination are not only affected by heterosexism, but also by racism, anti-Semitism, ableism or other form of structural discrimination which intersect with each other. For example, Jewish trans* people have different experiences compared to non-Jewish trans* people or Jewish cis people. Multidimensional discrimination refers to the intersection of different form of discrimination. For those affected, it is often difficult to identify whether the discrimination is due to their trans* identity or their membership to another marginalised group, as in intersectional discrimination, different forms of discrimination occur at the same time.

The General Equal Treatment Act (AGG) does not recognise multidimensional discrimination as its own form of discrimination, but states in § 4 that disadvantage on the grounds of several characteristics mentioned in § 1 (race, ethnicity, gender, religion, belief, disability, age, sexual orientation) is only justified if the justification applies to all the characteristics concerned. An expert report by the ADS of 2010 showed that multidimensional discrimination is often not analysed appropriately in court from a legal perspective.
