"Stupid Girls" is a song by American artist Pink, released as the first single from her 2006 album, I'm Not Dead. The song was written by Billy Mann, Pink, Niklas Olovson and Robin Mortensen Lynch and produced by Billy Mann and MachoPsycho.

The single entered the U.S. Billboard Hot 100 chart in the week of February 25 at number twenty-four, the week's highest debut and the highest debut of Pink's career (later topped by her 2008 single, So What). In the week of March 4, it climbed to number thirteen, becoming Pink's eighth top twenty single in the United States and her highest peaking single since "Just like a Pill" (2002). Its peak on the Top 40 Mainstream airplay chart, however, did not match that of most of her previous singles. "Stupid Girls" remained on the Hot 100 for sixteen weeks, and it reached the top twenty on the Pop 100 and appeared on the Adult Top 40. It received airplay in nightclubs, peaking inside the top twenty on the Hot Dance Club Play chart. "Stupid Girls" was certified Gold by RIAA on February 13, 2008.
