"Flavor of the Weak" is a hit single by the Boston, Massachusetts band American Hi-Fi from the band's 2001 self-titled debut album. It peaked at #5 on the U.S. Modern Rock chart and #41 on the Billboard Hot 100, becoming the band's biggest hit (and only appearance on the latter chart).

The title has often been incorrectly spelled "Flavor of the Week," due to the resemblance to the phrase indicating a featured weekly item that is widely used in several ice cream chains and independent shops.
