"Weak" is an R&B ballad recorded by the girl group SWV for their debut album, It's About Time (1992). It was written and produced by Brian Alexander Morgan, who composed the lyrics based upon his feelings towards R&B singer Chanté Moore. Morgan originally wrote the song for Charlie Wilson, but he later decided to give the song to the group. Morgan revealed that Coko didn't like the song and gave him attitude during the recording of the single.

"Weak" was released as the third single from SWV's album, following the top-ten success of "I'm So Into You". It sold over one million copies domestically and was awarded a platinum certification from the Recording Industry Association of America. "Weak" hit number one on the U.S. Billboard Hot 100 in July 1993 where it stayed for two weeĸѕ. It also topped the Hot R&B Singles chart for two weeks. Outside the US, the song also reached number six on the New Zealand Singles Charts; it went on to become their signature song.
