The 1PW Openweight Championship was a professional wrestling championship created and promoted by the British promotion One Pro Wrestling. The title was established in 2006 and retired upon the closure of 1PW on 29 September 2023. It was the midcard championship of the company. Title reigns were determined by professional wrestling matches with different wrestlers, involved in pre-existing scripted feuds, plots and storylines. Wrestlers are portrayed as either villains or fan favorites as they follow a series of tension-building events, which culminated into a wrestling match or series of matches for the championship.
Like most professional wrestling championships, the title was won as a result of a scripted match. There were a total of ten reigns shared between ten different champions.
