The University of Lethbridge Students' Union (ULSU) is a non-profit organization representing interests of undergraduate students studying at the University of Lethbridge.

The ULSU is not a university department; it is an independent organization, established in 1967 by the Lieutenant Governor in Council, of Alberta.

The ULSU receives authority to conduct business through the Post-Secondary Learning Act of Alberta(PSLA).

Councils in the past have held seats on other municipal committees.

Council members sit on numerous committees within the University of Lethbridge itself as well.
