"Wake Me Up Before You Go-Go" is a song by English pop duo Wham! which was released in 1984 and became their first UK number one hit. It was written and produced by George Michael, one half of the duo.

Michael's inspiration for the song was a scribbled note left by his Wham! partner Andrew Ridgeley for Andrew's parents, originally intended to read "wake me up before you go" but with "up" accidentally written twice, so Ridgeley wrote "go" twice on purpose. Released in May 1984, it heralded the beginning of a softer, sunnier image for Wham!, who had spent the previous year as a moodier, more politically themed duo, with songs about unemployment, young marriage, and battles of will between parents and their children. With the release of "Wake Me Up Before You Go-Go", they re-emerged with wider smiles, more colourful clothing, and a more positive disposition in interviews.

The song entered the UK singles chart at number four — after much hype from the duo claiming they would go straight in at number one, which was a rare occurrence then — and climbed to the top seven days later, staying there for three weeks.

The song also went to the top of the Hot 100 in the USA and Michael followed it up with a solo single, "Careless Whisper" and another Wham! hit, "Freedom", both of which were also UK number-one hits. The album, Make It Big, was an unqualified success. Wham! had three more UK number one singles and split at their height in 1986.

Another band, Babs & The Bopettes, sang phonetically by Tress MacNeille as Babs Bunny along with her friends, Gail Matthius as Shirley the Loon, Kath Soucie as Fifi Le Fume and Cree Summer as Mary Melody. The "Jitterbug!" part is by Charles Adler as Buster Bunny, Joe Alaskey as Plucky Duck and Don Messick as Hamton J. Pig. The chorus is when Babs Bunny lectures Gogo Dodo to wake Babs up before Gogo does. At the end, she laughs and says, "Well c'mon, do you want me to see Buster, or not?".

The music video, essentially the duo performing (it also introduced Ridgeley as a guitar player for the band) to a teenage audience, was memorable for the clothes, which became a lasting sartorial image for the 1980s as a decade. Michael and Ridgeley, plus backing singers Pepsi and Shirlie, along with motor trade Guru Peter (Froudy) Froud, were wearing Katharine Hamnett T-shirt designs which said "CHOOSE LIFE" (originally a slogan targeted at drug abuse and suicide) and "GO GO", which became much sought-after fashion items of the year. Michael was also seen in luminous gloves, which he later bemoaned as the clip of him always picked out by advertisers whenever "Wake Me Up Before You Go-Go" went on to a compilation album. The video was filmed at the Carling Academy Brixton in London.

The video was barely "spared retirement" from rotation on MTV when it was voted #11 on the network's worst videos countdown in 1999. During the video's commentary, co-host Denis Leary joked that he knew George Michael was gay when he first caught a glimpse of Michael's shorts.

On the other hand, Blink-182 listed the video as their all-time favorite.

The US 7" single (Columbia 04552) had the same track listing.
