The Undisputed British Heavyweight Championship is a professional wrestling championship owned by the Revolution Pro Wrestling (RevPro/RPW) promotion. The title was created and debuted on 16 July 2005 and is the promotion's principal championship. The current champion is Luke Jacobs, who is in his first reign. He won the title by defeating Michael Oku at the RevPro 12th Anniversary Show in London, England on 24 August 2024.
The current title was formed after the IPW:UK Championship and the All-England Championship were unified into the Undisputed British Heavyweight Championship, but later became known as simply the "British Heavyweight Championship" after RPW separated itself from (IPW:UK). The title has been defended in the United States and in Japan through RPW's working relationships with New Japan Pro-Wrestling (NJPW) and Ring of Honor (ROH). In 2018, the championship name was reverted to the "Undisputed British Heavyweight Championship".
Luke Jacobs is the current champion in his first reign. He defeated Michael Oku for the title at the RevPro 12th Anniversary Show on 24 August 2024, in London, England.
