"Get Down" is the debut single by Canadian boy band b4-4. It was released in May 2000 as the first single from their debut self-titled album, B4-4. The song was very successful in Canada, peaking at number 4 on Canada's Singles Chart. The song was featured on MuchDance 2001. The song's producers, Jason Levine and James McCollum, were nominated for "Best Producer" for the song at the 2001 Juno Awards.

Since its release, the song has become infamous for its suggestive lyrics, which are thinly veiled references to oral sex. Ed the Sock, a MuchMusic denizen, castigated the song as a "sugar-coated fellatio fest".

Ryan and Dan Kowarsky later admitted the song was about oral sex.

The music video begins with a young boy walking and seeing a homeless man on the street, who asks for money. The boy has no money and continues walking, until he stumbles upon a View-Master stereoscope left in the garbage. After looking through the lens of the stereoscope, he gains popularity and wealth as b4-4 dance and sing. At the end, he gives the stereoscope to the homeless man.

Ethan Klein of the YouTube channel h3h3Productions lampooned the song and its music video in a video titled "Ethan Joins a 90s Boy Band," uploaded on April 16, 2016. In the video, he also imitated b4-4's image and created a parody of the song with Schmoyoho. As of June 23, 2017, the video has over 4 million views.
