(A estrutura do CERN para o período 2026-2030 resúmese ao final da páxina)

O Consello do CERN (CERN Council) é a máxima autoridade da Organización e é responsable de todas as decisións importantes. Controla as actividades do CERN en asuntos científicos, técnicos e administrativos. Aproba os programas de actividade, adopta os orzamentos e revisa os gastos. O Consello está asistido polo Comité de Política Científica e o Comité de Finanzas. A Directora ou Director Xeral, nomeado polo Consello, xestiona o Laboratorio do CERN. A Dirección Xeral está asistida por unha estrutura  de Departamentos que xestiona o Laboratorio.

O CERN está dirixido por 24 Estados membros, cada un dos cales ten dous delegados oficiais no Consello do CERN. Un representa á administración do seu goberno; o outro, aos intereses científicos nacionais. Cada Estado membro ten un único voto e a maioría das decisións requiren maioría simple, aínda que na práctica o Consello busca un consenso o máis próximo posible á unanimidade.
