"Mo Money Mo Problems" is a single by The Notorious B.I.G., the second single from his album Life After Death. Released posthumously, the single topped the Billboard Hot 100 for two weeks in 1997, replacing "I'll Be Missing You" from the chart, Puff Daddy's tribute to the rapper's death himself. The song is Notorious B.I.G.'s second posthumous number one single, following "Hypnotize", making him the only artist in Hot 100 history to have two #1 singles posthumously.
