Celine was the second concert residency by the Canadian singer Celine Dion. It was performed at the Colosseum at Caesars Palace in Las Vegas, Nevada, beginning 15 March 2011, with an estimated 70 performances per year. The residency ranked 26th in Pollstar's "Top 50 Worldwide Tour (Mid-Year)", earning over $20 million. Being seen by over 200,000 people, the residency became the number one show in 2011. It made Dion the top earner in Vegas, earning $500,000 a show, and made her the "most profitable music act in Las Vegas" since Elvis Presley.

A concert residency is a series of concerts, similar to a concert tour, but only performed at one location. Pollstar Awards defined residency as a run of 10 or more shows at a single venue. An artist who performs on a concert residency is called a resident performer. Concert residencies have been the staple of the Las Vegas Strip for decades, pioneered by singer-pianist Liberace in the 1940s and Frank Sinatra with the Rat Pack in the 1950s.
