The Colorado Section of the Amateur Radio Emergency Service (ARES) is part of the Field Organization of the American Radio Relay League (ARRL), the national association of amateur radio.

The ARRL divides the nation into 71 administrative sections. The State of Colorado comprises one of these sections.

Each section is led by an elected Section Manager. The Section Manager makes section level appointments, including the Section Emergency Coordinator (SEC) who is responsible for leading Colorado Section ARES. Robert Wareham was appointed SEC in October of 2011.

The Colorado Section  is subdivided and organized consistent with the 9 All Hazards Regions implemented by the Colorado Governor’s Office. Colorado Section ARES has numbered its regions with North Central designated as Region 1, South Central designated as Region 2, and the remaining regions numbered in clockwise order from the Northwest Region around the state to Region 9, the Northwest Region. Each region of Colorado ARES has a Region Emergency Coordinator (REC) appointed who coordinates activities within that All Hazards Region.

Each Region of the Colorado Section is further organized into 1 to 6 Districts, typically using county boundaries. District Emergency Coordinators (ECs) are appointed by the Colorado Section Emergency Coordinator upon recommendation and nomination by the respective Region EC.
