Bissu is a gender identity and role in the Bugis culture in Indonesia. Bissu are often called "gender transcendent" and represent all parts of gender combined into one whole. Some (but not all) bissu are intersex.

Bissu is one of five genders that are recognised in Bugis culture. The other four are oroane (cisgender men), makkunrai (cisgender women), calabai (roughly equivalent to trans women) and calalai (roughly equivalent to trans men).
