The dumb blonde is a popular-culture stereotype applied to blonde-haired women. The archetypical "dumb blonde", while attractive and popular, lacks both common street-sense and academic intelligence, often to a comedic level. The dumb blonde stereotype is frequently used in the popular blonde jokes.

Numerous actresses have played characters labelled as "dumb blondes", famously including Jayne Mansfield, Marilyn Monroe, Marie Wilson, Judy Holliday (most notably in her Academy Award winning role in Born Yesterday), Suzanne Somers (primarily for her role as Chrissy Snow on Three's Company), and Goldie Hawn (for her persona on the variety show Laugh-In). The film Legally Blonde starring Reese Witherspoon featured the stereotype as a centerpiece of its plot. Country music legend Dolly Parton, aware of this occasional characterization of her, addressed it in her 1967 hit Dumb Blonde (though Parton's lyrics challenged the stereotype, stating "...just because I'm blonde, don't think I'm dumb 'cause this dumb blond ain't nobody's fool..."). Also, saying she was not offended by "all the dumb-blonde jokes because I know I'm not dumb. I'm also not blond." More recently, Paris Hilton has been characterized as a dumb blonde due to her public persona, which is portrayed by popular culture as promiscuous and self-absorbed, and Jessica Simpson has been seen as one due primarily to her behavior on her TV series, Newlyweds: Nick and Jessica".
