The International Classification of Functioning, Disability and Health (ICF) is a classification of the health components of functioning and disability.

The ICF received approval from all 191 World Health Organization (WHO) member states on May 22, 2001, during the 54th World Health Assembly. Its approval followed nine years of international revision efforts coordinated by WHO. WHO's initial classification for the effects of diseases, the International Classification of Impairments, Disabilities, and Handicaps (ICIDH), was created in 1980.

The ICF classification complements WHO's International Classification of Diseases-10th Revision (ICD), which contains information on diagnosis and health condition, but not on functional status. The ICD and ICF constitute the core classifications in the WHO Family of International Classifications (WHO-FIC).^: 3–4
