Wrestle Kingdom V in Tokyo Dome (レッスルキングダムⅤ ｉｎ東京ドーム, Ressuru Kingudamu Ⅴ in Tōkyō Dōmu) was a professional wrestling pay-per-view (PPV) event produced by the New Japan Pro-Wrestling (NJPW) promotion, which took place at the Tokyo Dome in Tokyo, Japan on January 4, 2011. It was the 20th January 4 Tokyo Dome Show and the fifth held under the "Wrestle Kingdom" name. The event featured thirteen matches (including two dark matches), four of which were contested for championships. Wrestle Kingdom is traditionally NJPW's biggest event of the year and has been described as their equivalent to WWE's WrestleMania.

The show included wrestlers from the American Total Nonstop Action Wrestling (TNA) and Mexican Consejo Mundial de Lucha Libre (CMLL) promotions for the fourth and third year in a row, respectively. During the show, the TNA World Heavyweight Championship was defended for the first time in Japan. The three matches involving TNA wrestlers were aired by the American company as part of Global Impact 3. Wrestlers from DDT Pro-Wrestling, Pro Wrestling Noah and Pro Wrestling Zero1 also took part in the show.

While NJPW announced an attendance number of 42,000, which would have been the largest audience at a January 4 Tokyo Dome Show in six years,Dave Meltzer claimed that the actual attendance number was 18,000, tied with the 2007 Tokyo Dome show for the smallest audience in the event's history.
