Teemat

Pääartikkeli: Teema

LEGO-teema, tai tuotelinja, on samantyyppisten settien joukko. Jokaisen teeman setit ovat samankaltaisia ja kuuluvat samaan "tarinaan". Teemat kehittyivät viralliseksi käytönnöksi 1970-luvulla jolloin kehitettiin ja julkaistiin viisi ydinteemaa: Dublo (1969), TECHNIC (1977), Town (aikaisemmin julkaistu tuotesarja vaihtoi nimensä), Castle (1979) ja Space (1984). Useimmat setit kuuluvat johonkin näistä ydinteemoista ala-teemoina mutta jotkin setit muodostavat omat sivuteemansa kuten Pirates tai Fabuland.
