The Greater Metro Conference is a high school athletics conference which consists of ten high schools near Milwaukee, Wisconsin.

The conference consists of ten schools, eight public, and two private.

The private schools (Marquette and Divine Savior Holy Angels) are all-boys and all-girls Catholic high schools respectively.

The WIAA-approved changes for the 2017–18 school year added Germantown High School and Wauwatosa West High School and sent West Allis Central High School to the Woodland Conference.

The move was hailed by locals as a decision that increased competition in a smaller geographical area.
