Wrestle Kingdom in Tokyo Dome (レッスルキングダム ＩＮ 東京ドーム, Ressuru Kingudamu IN Tōkyō Dōmu) was a professional wrestling pay-per-view (PPV) event co-produced by the New Japan Pro-Wrestling (NJPW) and All Japan Pro Wrestling (AJPW) promotions, which took place at the Tokyo Dome in Tokyo, Japan on January 4, 2007. It was the 16th January 4 Tokyo Dome Show and the first held under the new "Wrestle Kingdom" name. Wrestle Kingdom is traditionally NJPW's biggest event of the year and has been described as their equivalent to WWE's WrestleMania.

The show marked the 35th anniversary celebration for NJPW, who teamed up with one-time rival promotion AJPW to produce the show. Headlined by two title matches, contested for NJPW's top title, the IWGP Heavyweight Championship, and AJPW's top title, the Triple Crown Heavyweight Championship, as well as the reunion of Keiji Mutoh and Masahiro Chono, all in all, the event featured nine matches.

When New Japan Pro-Wrestling (NJPW) held the 2006 January 4 Tokyo Dome Show, Toukon Shidou Chapter 1, some saw it as a possible "end of an era". In recent years, the January 4 show, held annually since 1992, had been suffering from a drop in both interest and attendance and while the 2006 show drew 31,000 fans to the Tokyo Dome, only around 10,000 of them paid for their ticket. The show, however, was still considered a success due to high merchandise sales, allowing NJPW to keep the tradition alive for another year. NJPW had previously had success promoting interpromotional shows with All Japan Pro Wrestling (AJPW), and decided to partner with them again for the 2007 Tokyo Dome show in an effort to boost attendance numbers. The partnership was officially announced in a press conference on November 15, 2006. AJPW had recently partnered with Yuke's, the owners of NJPW, for the video game Wrestle Kingdom. As a result, the 2007 January 4 Tokyo Dome show was dubbed "Wrestle Kingdom in Tokyo Dome". The name stuck and the annual January 4 Tokyo Dome show has been known as Wrestle Kingdom ever since.
