"Drop It Like It's Hot" is a song by American rapper Snoop Dogg featuring fellow American musician Pharrell Williams. It was released on September 27, 2004, as the lead single from Snoop Dogg's seventh studio album, R&G (Rhythm & Gangsta): The Masterpiece (2004). The song was produced by the Neptunes. It is regarded as an iconic song, with Snoop performing the chorus and the second and third verses while Pharrell performs the first verse.

The song topped the US Billboard Hot 100 for three weeks, making it both artists' first number one on the chart. It was also Snoop's fourth top-ten as a solo artist, first since 2003's "Beautiful" (the others being 1993's "What's My Name?" and 1994's "Gin and Juice"). The song also gave him his first number one on the Hot R&B/Hip-Hop Songs chart. It also peaked at number one for four consecutive weeks in New Zealand, and number ten in the UK Singles Chart. It gained some critical attention for its minimal, extremely sparse production, consisting of tongue clicks, keyboards, a drum machine beat and white noise. It was nominated at the 2005 Grammy Awards for Best Rap Song and Best Rap Performance by a Duo or Group. Two songs "Jesus Walks" by Kanye West and "Let's Get It Started" by Black Eyed Peas respectively won the former and latter awards. The single was Pharrell's biggest hit worldwide, until 2013's "Get Lucky", "Blurred Lines", and "Happy", the latter being his biggest single as a lead artist.

On December 10, 2009, "Drop It Like It's Hot" was named the most popular rap song of the decade by Billboard.
