"Casanova" is a song by American R&B vocal group LeVert, written and produced by Reggie Calloway. Released as a single in 1987, it reached number five on the US Billboard Hot 100 chart and number nine on the UK Singles Chart—LeVert's only top-40 hit on either chart. It was the first new jack swing song to reach number one on the Billboard Hot Black Singles chart, topping the chart for two weeks. It has become a standard number for New Orleans brass bands following its popularization by the Rebirth Brass Band.
