"Never Gonna Give You Up" is a song written by Stock, Aitken & Waterman and sung by English singer Rick Astley. The song was released as the first single from Astley's multi-million selling debut album, Whenever You Need Somebody. The song was a worldwide number-one hit, initially in the singer's native United Kingdom in 1987, where it stayed at number one for five weeks and was the best-selling single of that year.

The song won Best British Single at the 1988 Brit Awards. The music video for the song has become the basis for the "Rickrolling" Internet meme.

In 2008, Rick Astley won the MTV EMA awards for "Best Act Ever" with the song "Never Gonna Give You Up", as a result of collective voting from thousands of Astley enthusiasts.

In the "Never Gonna Give You Up" music video, directed by Simon West, a smiling Astley sings and dances to the song in various outfits and venues in West London, sometimes accompanied by backup dancers. A bartender played by Clive Clarke gradually shifts from casually noticing Astley's singing to being fully engrossed in the song with energetic acrobatic moves. The athletic exertion of many of the other dancers also becomes more intense over the course of Astley's performance.

"Never Gonna Give You Up" is the subject of a popular Internet prank known as "rickrolling" involving misleading links redirecting to the song's music video. By May 2007, the practice had achieved notoriety on the Internet, and it increased in popularity after its use as a 2008 April Fool's Day joke by various media companies and websites, including YouTube rickrolling all of its featured videos on that day and a website allowing people to Rickroll their friends' phones.

In 'a couple of weeks', about 13 million people had been 'rickrolled' into watching Astley's video, the BBC reported on 1 April 2008. "I think it's just one of those odd things where something gets picked up and people run with it," Astley told the Los Angeles Times in late March 2008, adding: "That's what's brilliant about the Internet."

Rick Astley also appeared in the 2008 Macy's Thanksgiving Day Parade interrupting a song performed by those on a float promoting the Cartoon Network program Foster's Home for Imaginary Friendswith a lipsynched performance of "Never Gonna Give You Up".

In several of its protests against Scientology, Anonymous has employed The Rickroll.

Also known as the "Ultimate Rickroll". On December 1, 2008, a campaign was started on Facebook in an attempt to make the song the 2008 Christmas #1 in the UK as an attempt to "rickroll" the country during Christmas. The campaign's purpose was to stop the X-Factor from gaining the #1 Christmas spot, thereby ending the show's chain of success. The group attracted nearly 30,000 people in its first week active. Campaigners were encouraged to get as many people as possible to download the song from iTunes between the 15th and 20th of December 2008. The song only managed to peak at #73; however, this was later found to be a deliberate lowering of the song's place (having reached #3 a week before it came to its finish) due to the company's belief that "the songs [sic] ranking was ridiculous and rigging a contest was unfair on other artists". The campaigners, Jon and Tracy Morter, were ultimately successful the following year with a Rage Against The Machine campaign that hit the No.1 spot in December 2009

The Rickrollerz is a pseudonym used by a group of London dance producers that made a house music cover version of Rick Astley's 1987 song "Never Gonna Give You Up" on the day, and in honor of, the London Liverpool Street Station rickmobon April 11, 2008. In May 2008, the track entered the UK Club Charts at number 22.

On Friday 11 April, 2008 at 6 PM, a group of people made a "Rickmob" on the Liverpool Street station, inspired on the rickrollingInternet phenomenon. The song was remixed at the same studio as 20 years earlier, the same day.

The "Rickmob" was a spontaneous gathering where hundreds of people dressed as Rick Astley joined on Friday 11 April 2008 in Liverpool Street Station for a short rendition of the 80's superhit and then quickly dispersed.

They released their own single of "Never Gonna Give You Up" the same day.
