The Suite Life on Deck is an American teen sitcom created by Danny Kallis and Jim Geoghan, and developed by Kallis and Pamela Eells O'Connell. The series aired on Disney Channel from September 26, 2008, to May 6, 2011. It is a sequel/spin-off of The Suite Life of Zack & Cody. The series follows twin brothers Zack and Cody Martin and hotel heiress London Tipton in a new setting, the SS Tipton, where they study-abroad at Seven Seas High School and meet Bailey Pickett while Mr. Moseby manages the ship. The ship travels around the world to nations such as Italy, France, Greece, India, Sweden and the United Kingdom where the characters experience different cultures, adventures, and situations.

The series' pilot aired in the UK on September 19, 2008, and in U.S. markets on September 26, 2008. The series premiere on the Disney Channel in the U.S. drew 5.7 million viewers, and it became the most watched series premiere in Canada on the Family Channel. The show was also TV's No. 1 series in Kids 6–11 and No. 1 scripted series in tweens 9–14 in 2008, outpacing veteran series Hannah Montana and Wizards of Waverly Place in the ratings. On October 19, 2009, it was announced that the series had been renewed for a third season, which began production in January 2010 and debuted on July 2, 2010. The series was also 2009's top rated scripted series among all children ages 6 to 14

The series has been broadcast in more than 30 countries worldwide, and was shot at Hollywood Center Studios in Los Angeles (as was the original series). The series was taped in front of a live studio audience, though a laugh track is used for some scenes. The series is the second spin-off of a Disney Channel series (after the short-lived That's So Raven spinoff Cory in the House); as well as the last Disney Channel series to debut broadcasting exclusively in standard definition, and the first of three Disney Channel shows to transition from standard definition to high definition, which occurred on August 7, 2009, with the season 2 premiere, "The Spy Who Shoved Me", and the second multi-camera comedy (after Sonny with a Chance) to utilize a filmized appearance instead of the Filmlook appearance that was used in the first season.

On March 25, 2011, a film based on The Suite Life on Deck and its parent series, titled The Suite Life Movie aired on the Disney Channel. The series' forty-minute finale episode, "Graduation on Deck", aired on Disney Channel on May 6, 2011, officially ending the series.
