Dunbarov broj je teorijska kognitivna granica broja ljudi s kojim pojedinac može održavati stabilne društvene odnose. To su odnosi u kojima pojedinac zna ko je svaka osoba, te u kojem je odnosu svaka osoba sa ostalim osobama. Zagovaraoci ove teorije kažu da broj veći od Danbarovog broja općenito zahtijeva rigoroznija pravila, zakone i pojačane norme kako bi se održala stabilna i kohezivna grupa. Ne postoji precizna vrijednost za Dunbarov broj, ali često citirana aproksimacija je broj 150.
