“Superbad” is set in a vaguely defined suburban area that is clearly meant to be in the United States, and it’s generally understood to take place in the suburbs of Los Angeles, California , even though the movie never names the city directly.

The high school, houses, and party neighborhoods are all portrayed as typical American suburbs, and production notes and filming location guides confirm that the story world matches the LA suburban setting where it was shot (areas like El Segundo, Glendale, and the San Fernando Valley).
