Maryland Association of Counties

MACo is the non-partisan voice of all 24 Maryland counties promoting effective, efficient government through advocacy, education, and collaboration.

The Association’s membership consists of county elected officials and representatives from Maryland’s 23 counties and Baltimore City.

MACo’s members determine Association policy and positions on executive and legislative proposals through an elected Board of Directors and a volunteer Legislative Committee. Through MACo’s advocacy, training, education programs, and annual conferences, members are provided with endless opportunities to improve their capacity to serve their residents.

Thirteen organizations representing professional county government staffs are affiliated with MACo. These Affiliate Members work to enhance their members’ effectiveness and assist the Association in formulating its legislative agenda and in structuring conference presentations.

MACo is the only organization serving the needs of county elected officials and governments across the state.
