- 21 August — John Morrissey defeats George Thompson in the 11th round at Mare Island, California and claims the Heavyweight Championship of America, which has been vacated by the now-retired Tom Hyer. His claim is not generally recognised at this time because of the prior claim by Yankee Sullivan, who fought Hyer in 1849.
- Harry Broome retains the Championship of England but there is no record of any fights involving him in 1851.
- The United All England Eleven (UEE) is established as a rival to William Clarke's All-England Eleven (AEE). Jemmy Dean and John Wisden are the main organisers. Other players representing the UEE in its early years include John Lillywhite, Tom Lockyer, James Grundy, Frederick Miller, Will Mortlock and Tom Sherman.
- 27 July — John Sherman makes his final first-class appearance for Manchester v. Sheffield at Hyde Park Ground, Sheffield. His career has spanned a record 44 seasons from his debut at Lord's on 20 September 1809 when he played for Beauclerk's XI v. Ladbroke's XI.
